Quote from LunaranThe Quake1 crowd had a contest about a year ago to design a single player map that was constrained on x and y to 768x768, but not limited in Z. Made for some cramped maps, so maybe 768 was a little low, and it'd be interesting to see maps constrained on 'any two axes', or even any single axis.
That sounds like it could be really fun, especially with the vertical aspect...
Otherwise the 1024 contest always seemed like it'd be fun, same with most of these ideas I'm hearing.
