Once I would’ve placed Adobe Flash between these engines, but Adobe behaved so badly (with their customers – as I was – and with Flash in general) that now I simply shun for it, at least as a game engine.
There are obviously other engines, but Unity is the only one I use, so this list is quite short.
Cool C#/C++ Libraries
A list of tools related to Unity.
Essential (at least for me) Plugins
- 2D Toolkit
- Easy Save 2
- HOTween (tweening engine)
- Smooth Moves (character animation)
- Scoreoid (score system which simply works with WWW calls)
