I run a TF2 server, and I've noticed a problem in that there is maybe only one map I have in rotation that is suitable when only a few people are on the server. It's a dodgeball map, and I'd rather not have that be the gameplay that is the default for an idle server. Aside from that and one zombie map, the rotation pulls from the stock Valve maps. Are there any generally well received maps out there that aren't of a weird gametype that are well suited for fewer people? If I've overlooked a stock map, that would be ideal, but I'm wide open to suggestions.
Edit: I'm referring to maybe 6 or fewer total players here.
