I hated the map editor for Far Cry 2. It was a pain in the ass to use.
The only way a map editor for the consoles could work is if if gave you a checklist of sorts, a list of certain things you're map was required to have before it could work.
Like first you'd have to set up spawn points at either end of the map. Then you'd have to set up objectives A, B, and C a certain distance away from each other and so on and so forth.
ummm.. didn't Far Cry 2 have that?... I'm pretty sure there requirements for each gametype to work on your map. I'd gladly go back to working on my RP map (which is a single house so far btw), if people we're sure to play it, but the stress of working with something beyond my skills, and having ZERO reward for doing so (job well done doesn't count :verymad:).
Also I enjoy using forge mode on Halo, I built two maps, that I'm actually proud of.
