I've had a few conversations with people about this subject, and though I personally see the promise in using game engines; particularly cry and unreal because of their lighting and animation capabilities, the end user market is really geared more towards recreational artists and make art button pushers. For those that really know what they are doing in regards to figures, rigging, etc...it's just as easy to create what you want yourself and go from there.

Some would consider that re-inventing the wheel but there is more involved than just pressing fbx export.

Comitted to excellence through art.
