suggestions for fun mods?

[Merry Jolkar]

Is the system variability in FQM functional, or graphical? Qualitatively, how does it alter the game experience? And, if I create a map with FQM, but want to, e.g., play Pirates and Nomads on PBW, how can I create the game in the first place? Aren't the race modifications for Pirates and Nomads needed when I create the game? Or, is there some way to import a map made in FQM as the map I start with in my P*N game? Sorry to be so ignorant -- I am trying want to make sure that when I set up my next game, I know what I'm doing so the players won't mutiny!
Thanks!
