Nali Pali doesn't consist of just 1 map you know, it's a very good singelplayer though. And I can't really decide, it's like every map is something different unless the theme and archi is somewhat the same. So maps are things I can't compare, I like the Lastcrusade series, as well as deck_40, ctc-croon is pretty nice to, but the framerates are killing me instead of the bots. CTF-DeNovo, but that's a theme I fancy a bit less. I like CTF-Wether quite much.
I guess I go for ambients and a bit of gameplay.
