I am looking for another Mechwarrior 4 expansion pack game I would like to have for my birthday this year.  Since I only have Mechwarrior 4: Mercenaries, which game would be best for me?  I was thinking that I could try to get the Compilation Pack that contains two games and one that I already have, but I am not too sure if it is good enough.

Since those Mechwarrior games are not in stores anymore, my best bet to get another one of those games is by internet.
