When comparing Allegro vs WiMi5, the Slant community recommends Allegro for most people. In the question“What are the best 2D game engines?” Allegro is ranked 12th while WiMi5 is ranked 70th. The most important reason people chose Allegro is:
The Allegro community has produced a lot of great tutorials and resources. Allegro [Wiki](https://wiki.allegro.cc/index.php?title=Main_Page), Mike Geig's Allegro [Tutorials](http://fixbyproximity.com/2d-game-development-course/), Rachel Morris' [Tutorials](https://www.youtube.com/watch?v=E4RqHtEAAds), CodingMadeEasy's [Tutorials](https://www.youtube.com/playlist?list=PL6B459AAE1642C8B4&feature=plcp).
Specs
Ranked in these QuestionsQuestion Ranking
Pros
Pro Supports desktop and mobile
Support for Windows, Mac OS X, Linux, iPhone, and Android

Pro Good engine architecture
Allegro is well designed, easy to use and has many useful features.
Pro Good documentation and lots of tutorials
Since it has been in development since mid-90s with hundreds of people contributing to both the engine and documentation, it has all of its bases covered when it comes to standard support.

Pro Per-platform library optimization
Allegro uses DirectX for Windows, and OpenGL for other targets.
Pro Freedom to implement your own game engine
You are not bound to the limits of existing game engines, and you can actually implement your own engine.
Pro Versatile flow diagram script model
WiMi5 integrates a powerful visual scripting solution based on Blackboxes that allows you to create the logic flow of the game. You don't have to code (if you don't want) but you can also do it. WiMi5's actions and behaviors 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.
Pro Integrated servers
WiMi5 provides integrated back-end services, with tools available to save game session data, manage rankings, etc.
Pro Free development
The WiMi5 platform is free to use, supported by post-publication royalties.
Pro Built in monetisation tools
WiMi5 provides features to manage in-app purchases and micropayments. Virtual Goods management is integrated into the Logic Editor.
Pro Publication partnerships
WiMi5 maintains partnerships allowing simultaneous publication to a number of Web and mobile stores, all managed through the WiMi5 platform.
Games can also be downloaded and publish it wherever you want: in your own server or with your own partners. Just check the Download feature in the settings of your game.
Cons
Con Learning curve for hobbyist developers
Hobbyist developers coding alone may experience a learning curve with Allegro of about 200 hours (if you are rusty on C++). To learn quickly, see Mike Geig's tutorials at Fix By Proximity. This learning curve may be fine if you are considering going professional, but are still unsure.
For hobbyist developers not planning on going professional, you may want to look into a complete 2D game engine, rather than a coding library. For example, there are "non-coding" engines that provide support for coded plugins or scripting. But, if you are a dedicated hobbyist planning to use Allegro as your coding library of choice, you can still develop great games as a hobbyist.
Con Isn't great for C++
If you are a fan of object oriented programming, and want to use this library, then the chances are that you are going to be creating a lot of wrappers for functions in this library.
In short, if you're a C++ person, it could be recommended to check out SFML instead.
Con 30% royalties
For filling the engine, publisher, and back-end service roles, WiMi5 takes 30% of game revenues.
