at the moment blender's game engine can't compete with gamestudio at all. it's very nice though that it is fully integrated into blender. working like this could be great if it were a better engine.



True, the current BGE can't compete with GS (if we discard the workflow) but there are several projects that are striving to make BGE better.

However there has been a lot attemps to improve the BGE in blenders history so there is no telling will these succeed or not...
