Don't bother with HOMM V? I was just investigating the possibility of buying that game. It turns out that Ubisoft are about to release all HOMM V and the 2 expansions in one budget disk (That's Hot range) which will be like $20 for me! So why shouldn't I play HOMM V?
I think I saw a HOMM 3 + 4 complete DVD a while back...
