I tend to build my own. You should ask this in the general HL2 area where people who can't/don't want to/currently don't build their own maps if they had any good ideas they wanted to see built.
Make me Q3DM17, now! I really want that map. I don't know how many people I have asked... but none of them could do it... you sound like a good map maker , you could make it for me, couldn't you?
Actually no, he doesn't sound like a good map maker judging from the thread.
Anyway, I know this excellent map from Q3 Arena where you'd jump around on them little platforms. Would work wonders for HL2DM, but I'd need to make news textures and stuff... You know... Stuff I hate...
