If your going to use it for your own games m8 i suggest uploading them to mixamo and rigging them from there then if you have fbx2gg as long as the poly count is less than 22k you can import it to GG that way, if not you maybe want to try out simplygon to decimate. If you intend to try to sell it then Blender is the way forward theres some good tuts on here for it and some good modellers that use it Bod, Graphix and Belidos use it to good effect maybe worth asking them
