For 3D game studio :
I use the great plugin of Ventilator (thanks again ventilator).
It works great, and Blender is lot lot more advanced than
Fragmotion or milkshape smile

All affordable engines should support Blender Format also, caus it's free : anyone can download and use it right now !
and it's really Powerfull :
modeling ,animations,sculpting,normal map baking, retopology, UVW Unwrap, texture paint etc ...
