I've been looking on FPSB and seen loads of good looking custom TF2 maps with custom game modes and such, that (i think) would be worth having a play on:

King of the hill with random CPs... looks shiny: http://www.fpsbanana.com/maps/70786

DOM maps, played canalzone on TF and it's great: http://www.fpsbanana.com/maptypes/3596

CP+PL=Win: http://www.fpsbanana.com/maps/69011

Dodgeball is a laugh: http://www.fpsbanana.com/maps/51290

Glass war for TF2?: http://www.fpsbanana.com/maps/38509

Destroying cores...looks different: http://www.fpsbanana.com/maps/66102 (watch the video)

& i know it's not that special but theres a new version of DB_HEIGHTS!: http://www.fpsbanana.com/maps/70639

DOM maps are cool, KOTF is really fun, but I haven't tried the other types

Some o those look pretty cool!
