In FH1 I LOVE Berlin Streets but even when I see it coming up on rotation on PFC or TDP it more often than not gets changed to something else at the last minute(I'm guessing this is because many others do not like it). Sometimes I'll only be sticking on the current map because I see that coming up...only to have it get taken away
(makes me miss the days when wolf had an occupied FH1 server. The admins did not willy-nilly change the nextmap. If you typed !nextmap at the beginning of a map, you pretty well knew that WOULD BE the next map).
In FH2 I would have to say one map I really like but others seem to hate(atleast whenever I see forum posts asking for people to vote for maps they like and it comes in near the bottom) is Mersa Matruh. I have always liked this map but it certainly does not seem to be a popular one. It seems to give plenty for both tanks and infantry to do. I Love fighting between those top three flags as infantry.
There's a couple maps in FH2 that make me want to disconnect when they come up so I guess that means I 'hate' them and those would be Alam Halfa and aberdeen. But I think most others hate those too, so they're not good examples of one's i hate but others love for the 'vice versa' part of this post
