The best current solution is to use FPS Creator v1 along with FPSC 2 AppGameKit (both can be purchased on www.thegamecreators.com).
Works great! Create a level in FPS Creator (you can use any existing model pack or create your own segments, tiles, etc) and then build the level. FPSC 2 AppGameKit then loads the built level and converts it to a readable AppGameKit script. From there, add joysticks, buttons, AI, etc.
The only negatives are .obj only, so no rigged objects (yet). In the next AGK2 landmark, they will be adding terrain, vertex editing and .x import, which allows for rigged objects. Once that phase is ready, true 1st and 3rd person games in AppGameKit will be a reality.
