these awards are serious business

Here's my vote.

Best tileset: Desolation by BlurredD. One of my favourite tilesets ever, even though it's sort of new.

Best CTF: Unconventional Coffee by FireSword. This is just the kind of level FS is good at making. It might not be perfect, but it's really fun and I like it more than any of the other 2007 ctf levels I have played.
