GLBasic is fully featured for creating 2D games, and it also contains a complete 3D engine as well, using OpenGL.
GLBasic is updated extremely often by it’s developers.
It’s FAST and easy, which is always a great combination.

Networking is an easy process with GLBasic.
You can make your own online games!

Some of the 2D features are:
Sprites rotating, zooming, and blending,
polygonal sprites, and alpha blending

Some of the 3D features are:
GLSL shaders, real time shadows, Dot3 bump mapping, supports common 3D formats, light mapping, real time lighting, collision detection, and a lot more!

GLBasic is not free, but there is a fully featured trial version. The only downside to the trial is it will limit your gameplay to five minutes, and contains watermarks.

If there is some interest, I may create some tutorials in the future for starting GLBasic.
I plan to migrate evilmana.com away from a “PSP only” site, and GLBasic would be a great place to start!
