When comparing Corona SDK vs AppGameKit 2.0, the Slant community recommends AppGameKit 2.0 for most people. In the question“What are the best 2D game engines?” AppGameKit 2.0 is ranked 20th while Corona SDK is ranked 27th. The most important reason people chose AppGameKit 2.0 is:
The AppGameKit Basic can now export to HTML5.
Ranked in these QuestionsQuestion Ranking
Pro Very simple to use
Corona SDK is completely free. That includes pro-tier plugins.
Pro Corona Simulator
Corona SDK ships with Corona Simulator, which runs your game/app directly on your PC/Mac and updates every time you make changes.
It provides immediate feedback to your actions, you can see your changes right on the screen, without necessity to make build to device. Getting instant feedback really boosts tenfold prototyping and development speed.
Pro Lua syntax
Uses the great and easy-to-learn Lua programming language.
Pro Good documentation and lots of tutorials
Pro Very comprehensive API
It's very quick to get things up and running with Corona SDK. The API is extensive and while it's not 100% feature-complete with the iOS API, it's close enough that you could create tons of games and never run into a roadblock.
The API docs can be found here.
Pro Amazing learning curve
Corona does not throw photoshop-like madness full of buttons editor. You can go as fast as you want, learning and building game from ground up. Eventually, you'll learn how much corona is doing for you. But to start you don't have to master complex editor software. It's a great tool to learn to start game development if you want to learn how to program and make games. Your experience will be 100% transferable to any other Pro game engine.
Pro Cross-platform desktop and mobile
Corona works on OS X, Windows and Android (including Kindle Fire & Nook).
Pro Live builds - update builds running on a device automatically
With the live build feature, once you have created a build and installed on a device, you get lightning fast turnaround times because any change on the code or data is updated to the devices running the game (within the local WiFi) immediately. So changes can be tested on the real hardware within a very few seconds.
What's even more impressive, this even works flawless with multiple devices running the game. You have to use it to learn how good of a feature this is while development and even more, while doing QA. Imagine fixing bugs and everyone of your QA team/friends/whoever helps to get your game done, has all changes on his device without doing anything but waiting 5 seconds - outstanding.
Pro Content scaling
It's easy to create a game that looks good on many different sized mobile devices.
Pro Marketplace for 3rd party plug-ins
Pro Great community
Pro Ability to call any native (C/C++/Obj-C/Java) library
Pro Well supported
Pro HTML5 support
The AppGameKit Basic can now export to HTML5.
Pro Instant testing on multiple devices at once
AppGameKit supports instant testing on all connected devices. With the push of a button you can run your game on any device connected to the development machine.
Pro Cross platform
Supports developing games for Android, iOS, PC, Mac, Linux and now HTML5.
Pro Easy basic programming
Program in tier 1 BASIC programming for every 3D game need.
Pro Raspberry Pi free version available
A Raspberry Pi version is available and free. Users just need to register with the developer and then they can download.
Pro Very fast compilation
It is a compilation based language, but the compilation is very fast. A project of about 1800 lines of code, for example, can compile almost instantly. (That's because it does not compile, it's an interpreter)
Pro You only need to to pay for the license only
There is no charge for upgrades, or for extra platforms (the HTML5 version just appeared in the latest version), there are no subscription fees or other usage charges. If you publish onto either Apple or Google's stores you will have to pay their costs, of course, but the makers of AGK do not take a cut of this themselves.
Informed, timely and intelligent feedback from the AGK forum.
Pro Fast development
There are plenty of functions which facilitate development and deployment. For example, the AGK player immediately plays the updated bytecode on Android devices then the online site helps with building an APK file for Google Play Store in minutes.
Pro Uses a powerful scripting language built for game development
Software produced with the App Game Kit is written in a language called AGK Script. This language has powerful inbuild commands including commands for 2D graphics, physics and networking. The commands make use of the platforms' native functions to improve performance. They are also designed to enhance code readability. The AGK Script commands have extensive online documentation.
Pro C++ and Basic, you have the choice.
It runs fast with BASIC but if you want more you can use C++, it's also easy to use.
Pro Can be used for advanced games programming in C++
Libraries which provide the same functionality are available for the five platforms, so you can code in C++
Pro Comes with an Integrated Development Environment (IDE)
AGK comes with an Integrated Development Environment (IDE) based on the Code::Blocks IDE for writing AGK scripts. A key feature of the IDE is its ability to broadcast compiled programs to other devices for testing.
Pro Excellent documentation
Every function is fully documented with examples and exercises. The Tutorial PDF is a full Introduction to 3D game programming with integrated references to every functionality and its most important usecases. The documentation is regulary updated.
Pro Plugin support for Windows
Plug-ins can now be added to the Windows platform. Create your own Tier BASIC commands and call them using the AppGameKit Basic script language style.
Con Closed source
Since you don't have access to the code, you can't make changes to the SDK. You even have to implement workarounds on issues that have long been reported, but never fixed.
Con Free, but not completely
Such important plugins like AdMob cost $300 per year!
Con Making a device build requires internet connection
To build your app for the device (iOS/Android/AppleTV) Corona requires to fetch resources from online. This would include base application template and plugins. This allows not to perform local build or use Xcode or Android Studio to do a build. Even Large games/apps would build very fast with good internet connection.
Your code never leaves computed. Corona SDK would transfer some information to determine which plugins and pieces has to be transferred in order to make a final steps in build.
As a bonus - you get basically one button press to get from your Corona Simulator game to game on a device.
Con Terrible scripting language
MS Basic from the 70's has more features. Procedural, no OO, inheritance, basic user defined types with overloading. Nothing. It even has GOSUB.
Con BASIC language
Even though it supports C++, it's mostly C++ mapped to BASIC without OOP.
Con Can almost only do trivial games
The editor is rather limited, not fully polished, and 3D is missing some key functionalities (3D is work in progress).
