When you present Solarus, you may use the following wording:
Solarus is a multi-platform, free and open-source 2D game engine, written in C++. It is primarily dedicated to Action-RPGs, also called Zelda-likes, but can actually do much more.
- Please avoid presenting Solarus as a The Legend of Zelda ™ engine. It has built-in features for Zelda-like games for historical reasons, but you can do any kind of 2D game now.
- Please avoid presenting Solarus as Super Nintendo™ emulator or ROM hack. It is an engine buit from scratch.
Always prefer the frame versions over the frameless ones.
