The only problem right now, is that they all have PFC Mapping team brand on them, so I am definitely NOT sure if we can use them.
Yeah, I didn't think of that. I see it as a problem in a different way: it's like an advertisement for an organization of people with a reputation for dishonest, fraudulent and cultish behavior, which can harm people who have no clue about this. So I'm definitely against accepting any such brands displayed anywhere on maps, unless it's a completely historical brand and in historical context
Anyway, those maps are not needed. The original maps they are based on can be used to create new FHSW versions of them (with new names, not that they'd conflict with obsolete maps which no one plays). I think Peenemunde would be cool (hopefully with the Wasserfall guided missile)!
There have already been many FHSW maps based on SWWWII, RTR, BFVietnam and other games' maps.
