I'll give some feedback on FH1, there is usually 2 servers with around 40/50 players in Euro evenings and 1 with around 10 players. The only pity is that all servers only play the popular maps (Normandy 1944, Ostfront 1945, Pacific 1945, Holland 1944) so yes, for a moment it's fun but it gets boring soon. In FH2 there is a much greater variety with maps.

You've heard Hockeywarrior, people! Pack your stuff and get in line, move out. Keep walking until we reach the first rendezvous point, men with arms stay behind to repel any attackers. Good luck and godspeed!
