Well, my buddy and me over at FS (where we first discussed this) intended it mostly as a "just for fun" project. The playability issue is there, and as I said, ground rules would have to be laid down (like respecting the climate and theme of the existing sections). I suppose another good idea would be to not place control points, spawn points or vehicles, for then to look at the map when it was finished and work out a game mode from there.
Sure, for an official map it'd be a dubious plan at best. For a "just for fun" project, though, I think it has potential.
TS means that the whole map (gameplay included) needs a defining trait. With more than one person making it, they might have different ideas what the map should be like, so it will play like crap.
Oh damn... so sorry. Here I was, so frustrated I couldn't explain what I meant properly, and it turns out I was the one who didn't get it all along
