Games w/ Map Creators

Hello all.

I've been looking for some more online Xbox games with map editors/creators/makers, whichever you like to call them.  I have Far Cry Instincts and Evolution, TimeSplitters: Future Perfect, and Gregg Hastings' Tournament Paintball, and I know about Pariah.  I am looking for some more games with map map creators; any genre will do.  It is just a coincidence that the ones I've listed are FPS'es.  Can ayone help me out here?  Remember, it needs to be online.  Thank You! 

Also, if you know of any 360 games w/ map editors (Besides FCIP), feel free to list them as well.

Can you share maps online with Tony Hawk's AM?

GS review trashed the game on old graphics and sound.... but will still be a cult forbidden>

XBOX Operation flashpoint: Elite (Tac Shooter) - overlooked game of the year for the PC the Xbox version took to long to come out and was forgotten. Mission/ map editor place tanks, troops, buildings, helicoters, people, sounds, draw distances weather, time of day, etc....andymc4610

yeah, that has a grat map/misson maker, i was just playing it, the one in far cry was also pretty good, but i'd take elite over far cry any day, it was HIGHLY underated.
