In the question“What are the best 2D game engines?” Unreal Engine 4 is ranked 17th while Clickteam Fusion 2.5 is ranked 31st. The most important reason people chose Unreal Engine 4 is:
Blueprints are authoring tools designed for non programmers so designers and other team members can help tweak and prototype. UE4's Blueprint scripts resemble flowcharts where each box represents a function or value, with connections between them representing program flow. This provides a better at-a-glance indication of game logic than a simple list of events, and makes complex behaviors easier to accomplish and games a lot faster to prototype.

Runs well under high object numbers, particularly on PC and iOS thanks to hardware acceleration.
Pro Great IRL user events
Clickteam holds user conventions for customers to come along, meet the staff and hang out with people who they've met online. This furthers the community spirit which is so prevalent around Clickteam's products and it's a fantastic weekend.
Pro It is very powerful for making 2D games, yet requires no traditional programming experience and very little to no higher math
There is no 'easy button' program that will make a good game for you with no hard work, and this software is no exception to that, but it does make the process easier. With the option of coding in either a spreadsheet style editor or a list style editor, the event based programming language reads more like English than traditional programming languages. This has made it ideal for me as I have a very hard time understanding traditional programming. I would say this is the perfect solution for people that want to make 2D games but who don't have a very mathematically oriented mind, and think more visually. Just like anything it can take some getting used to, but after following some tutorials and tinkering with it, you'll be able to create practically any kind of 2D game with it so long as you have the determination.
Pro Exports native mobile code, making great performance games
Pro Great for non-game apps
Such as tools, utilities, multimedia projects, etc.
Pro Great online store to get free and paid assets
Pro Can create custom extensions
Pro Visual (HLSL) effects
Pro Great formula editor, which allows you to create complex maths and events with ease
Pro Box2D physics engine
Pro Stable
Have used fusion 2.5 through all of its iterations, even when it was owned by imsi as CNC ( click n create ) it has been very stable and projects have been known to run on almost any Windows based computer. The projects you create even run on future versions of Windows with never many issues.
Pro 3D powerful solution
Cons
Con Very high build size
A blank project will build in to a minimum of 200 MB.
Con Slow
Compared to other engines, UE4 seems to perform various actions considerably slower. Actions like starting the engine, opening the editor, opening a project, rebuilding shaders, updating references, calculating lightmaps, saving projects, etc take long enough to get irritating and end up wasting precious development time.
Con Extremely long build times
Making a full rebuild, including engine can take a good 30minutes. If you plan to use Unreal professionally, you better get some licenses for Incredibuild as well.
Con Hard engine for beginners
This engine not easy for beginners
Con Steep learning curve
Especially when compared to its primary competitor, Unity.
Con No drawcall batching, performance is very bad on mobile
There's no dynamic batching support to minimize drawcalls. There's InstancedStaticmesh concept in UE4, but it's 3d only, functionally limited and requires hardware support which rules out most mobile devices.
Con C++ - oriented development cycle: slow turn-around times
The Unreal Editor is the main place to do stuff (of course), so if someone wants to do a lot of C++ stuff, the compilation and linking turn-around times can be painful. Still they probably are quite fast in comparison to the provided featureset.. Still ,they are far from optimal.
Con Poor documentation
Most of the "documentation" for code is actually just automatically generated from the source. If you're interested in knowing how things are supposed to work, you must either go to their answers site or pay for UDN.
Often their examples won't even compile, since they were written for now outdated versions.
Con Royalty based
5% of profits will go to Unreal after $3000 earned in a quarter.
Con They spend more time adding features than fixing existing ones
Con C# not natively supported
UE4 does not support C# natively, but this can be achieved through MonoUE, although it requires using the MonoUE fork instead of UE itself.
Con Poor source control support
Merge tool is not working.
Con Poor quality assurance on their releases
After each release they almost immediately release a hotfix. And another one. And another one.
Con Unreal Engine crashes a lot if you don't have the required system requirements
Con Sparse Resources for C++
C++ happens to be the main suite for Unreal, yet the documentation is very, very sparse.
Con Extremely poorly designed
The code is a mess.
Everything is connected, a single Actor is 1500 bytes, because it contains a million things that Epic once needed in a game.
Inheritance for AActor: AActor > UObject > UObjectBaseUtility > UObjectBase
Con Difficult for Mac users
If you're installing it on Mac, you simply download Epic games launcher and watch it download nothing endlessly.
Con Tutorials do not go in-depth enough
The blueprint tutorial just teaches how to turn on a light when you press f.
Con Proprietary
Con Not available on Linux
Con No Terrain Editor included
Con Bad support
The epic games team only assists with billing and account issues, not bugs.
Con Terrible physics
Con Frequent crashes
Often the editor crashes interrupting your work.
Con Poor error messages
Con Rarely works
Con Some features are really outdated and major updates are few and rare
There are some features that could make the software a lot more powerful but Clickteam does not have the staff resources to handle updating the software to be competitive with similar software.
Con Its Event Editor can be cumbersome if you are working on complex projects
While Fusion's visual programming event system is great to simplify things, it can be much more cumbersome to work with it than reading lines of code when you are working on a complex project. Especially if your events involve many nested conditions and lots of objects on the frame.
You are able to group events and objects, but it doesn't help at all if there's lots of conditions on an event and it becomes pretty hard to read.
Con Many extensions not available on non-Windows platforms
A lot of community-made extensions are only written for Windows, making it hard to port your game to other platforms.
Con It is very expensive
100$ to $400.
Con Many event 'gotchas', especially with object selection
Many events have very unpredictable selection behavior, e.g. the 'Create' action (where the selection depends on whether a selection list already exists).
There is also a lot of subtle selection behavior, e.g. implicit object pairs for actions when an object is used in an expression.
Con No native animator with curves, etc
Con Poor native movements
The native non-physical movements are practically unusable if you don't want to use Box2D physics in your game.
Con Need to write C++ extensions when existing extensions don't cut it
If you need e.g. a Steamworks extension or 3D display extension, you need to move out from the event system and create extensions in C++ with a cumbersome API. Fusion does not have FFI calls like other programming languages.
Con No animation/object hierarchy
You need to position/rotate objects manually.
Con Cannot script editor
You cannot script the IDE or editor with e.g. macros or custom functionality, like you can in other popular game engines.
Con Slow event system
Since the event system is interpreted, complex frames will start to slow down. This is also caused by poor code reuse, as usually, you need to copy+paste events with new conditions, making it impossible to cache intermediate results.
Con Lack of native network multiplayer system, built-in database support, social media support
Con Exporters are separate purchases, and they are not cheap
Con No console/Linux exporters
Up to now, Clickteam has a console convert service.
Con Simpler than Scratch
Fusion 2.5 is more Simpler than MIT'S Scratch!
Con The free edition is severely limited
