Possible to export/convert maps to play on other games?

[X-20]

Title says it all, Im working on a little 3d game project of my own right now. But i want to know if its possible to export a gtk map or convert one so it can be played with other games.

Thanks.

Yes...

But if it is compiled, you would need to decompile it.  The easiest way is if you have the .map.

NOTE:
If you are porting to/from a non quake-based game, it may be much harder.

Easiest thing to do would be to implement Q3BSP into your engine, and it might make converting maps a little easier.
