I'm playing around with a program called RPG Maker 2K. Before you get too excited, RM2K is VERY VERY basic. We're talking Nintendo-esque graphics... BUT you can make custom graphics for EVERYTHING. I am working on a project with this program and have managed to improve the graphics somewhat. I'm doing all the location/set graphics in Bryce and the characters are designed and rendered in Poser, then converted to a usable format for RM2K. So you CAN use Poser graphics with this, but it's strictly for RPG games, and you're in for a lot of work with converting the images and learning the different features of the engine, etc. In the end, it still looks like an old console game, but you don't have to program anything. You're probably looking for something 3D/FPS related... the RM2K community may be able to help with finding something. I know Quake and SWAT 3 use 3DS models, so you may want to look into learning that program if you want to do game models.
