Snowy forests and regular forests for me. Just like as Twisted said up there, really. x3
Also, I see no one has mentioned this at all, but I actually really enjoy exploring city/town maps and the like as well. Perhaps if the snowy forest and city/town theme were mixed, that'd be one of my favorite maps - I never seen a map like that, actually, so that'd be a cool idea for the future. Maybe I can try at making it myself as well.
