I don't think you'll find any spectacular games made with 3DGM as it's a very simple tool, however there are plenty of brilliant games made with Darkbasic and Darkbasic Pro: The
Evochron Games and
SoulHunter to name just two. It's hardly a difficult language, but it's very versatile. It's also not much more complicated than the FPSC scripting system, and most of the really good FPSC games take advantage of addition scripts anyway.
Take a look at
Program Announcements for more programs and games, and make sure to look way back because there's some pretty amazing old stuff in there.
