Making a game engine or just a game?
If your making an entire game engine (which is what 3DGS is) then your in the wrong forums.
Otherwise, if your looking to make a game using the 3DGS engine - then your in the right place. There are plenty of resources around here to help get any genre of game started, with a variety of dedicated websites hosting tons of codes/textures/models/levels/etc. for your personal needs. On top of all that the entire community is here to help with whatever problems your having.
Keep an eye on the manual as well, make it your best friend! Hope this has helped a little, if not give a little more insight on what your looking to do.
