Maybe take a look at these (free) programs:
-Not sure you'd like this one but, Reality Factory (http://www.realityfactory.info/cms/)
-ShiVa is a bit processor heavy, but it looks nice (http://www.stonetrip.com/)
-If want to make a fps game, use SilentWalk (http://www.silentworks.hu/index.php) Its not in development anymore due to the developer moving onto a new game maker thats less "fps only" and open source, but whats already there is probably much better than FPS Creator
-and if you happen to own a mac, Dim3D (http://www.klinksoftware.com/) looks awesome (editor is mac only but at least the games run in windows)
For ease, ShiVa looks like the best one to use, but the free version only lets you share your game with other people who have ShiVa or ShiVa player I think. Other than that, its completely free
However, if you want to make any type of 3D game, and make it exactly how you want, id recommend learning to program in something easy that still ends up looking fairly decent. For example Blitz3D (http://www.blitzbasic.com) or its free alternative called Ninfa3D (http://www.mysticrealitystudio.comuv.com/index.php?p=3_1) engine, its amazing and is also constantly in development (Even supports builtin physics, shadows and shaders )
