MonoGame vs HeroEngine

Support for iOS, Android, Mac OS X, Linux, Windows (both OpenGL and DirectX), Windows 8 Store, Windows Phone 8, PlayStation Mobile, PlayStation 4, Xbox One, Nintendo Switch, and the OUYA console with even more platforms on the way.

All the code is available to you ensuring you'll have the ability to make changes when you need to or even port to whole new platforms.

The framework implements the XNA 4 API, so games made in XNA can be ported to other platforms using this. This was the same API used by the Xbox Live Indie Games platform so there's lots of documentation online for it.

By leveraging C# and other .NET languages on Microsoft and Mono platforms you can write modern, fast, and reliable game code.

The community MonoGame has to offer is helpful and mature.

The performance on desktop platforms matches that of C++, but you still get all the pleasant features that C# has to offer.

Backend completely handled by the team at Hero.

No need for Perforce, Github or any other versioning software. It is built in. Check, Compare, Merge, revert, etc.

Developers of the engine and game developers are active on the Forums and Skype for private messaging.

Able to create many types of games and scales all the way from a single area up to a full-blown MMO.

Designed for the needs of a MMO. HSL is also relatively easy to learn as scripting languages go. It was geared towards beginners, not time hardened programmers, and as such, its easier for a novice to pick it up sometimes, than a c++ programmer. That, and it was intended to be "readable" more like English.

Skype channel and forums questions answered by developers of HE and users very quickly.

Though the export pipeline may be different and currently requires 3ds Max or Maya, the format is highly optimized to reduce high quality models down to KB's.
