I enjoyed Battlefront. But felt 1 didn't have good enough vehicle play whilst 2 somehow broke the infantry. Overall I don't think either was as good multiplayer as BF:Modern Combat.
KoToR is an epic, amazing game. The only problem I have with it is that, take the Star wars name off the box and there is very little to associate it with the Star Wars universe, it's not really connected to any canon so I can't have my fanboy nerd moments. I realise the game centres around Jedi/Sith war but really they could be any generic light/dark factions.
X wing-Tie Fighter series is best. Good gameplay, set in the right time period and full of uber-nerd moments.
