Resurrecting Wings...

[Extrudeface]

I believe these days, even UE4 (fbx 2014 only), static meshes (well, fbx supports skeleton animation, too) are imported there by FBX format, but i could be wrong...

Blender exports FBX, but there has been recently a somewhat active discussion about the idea of not supporting it anymore, for being a closed format, and mostly, for being a bit of a nightmare for coders (I believe part of it due to its ever changing nature and many versions. and as is not open, all is harder. )

Wings had FBX exporter for a while...anyway,there are many paths around it, there's a few utilities, converters, where you can import an OBJ and export a FBX, if is just a static mesh.

Blender devs might feel better in continuing the support of collada, but this is only what I suppose, this last bit.
A pity, as FBX is used largely by many game engines, a very dominant standard.
