Have a look at my StarCleaner game (signature). It's all done with Slick and MarteEngine (again: see signature) and not too much of OpenGL.
Complete source code is available as part of MarteEngine in the test directory tree.
Feel free to rip what you like
Thank you. Will definitely have a look when I get the chance.
I may not have stated myself clearly. It can include OpenGL, but it should not be hard to use. I was hoping for a trick in slick, where you do not actually see the GL bindings, if you dont want to:-)
