I have not yet played the game, so I'm reserving complete judgement until I can play the full pc game myself this weekend. However I plan to skip single player until I can see ROTS in late May (to avoid more Episode III spoilers). Of course this means MP better be good for me to play it from now until ROTS! ; )
Incidentally I'd have put a warning up for the spoiler you posted, but since it's very minor (not Episode III based, the very first level's location) I'll let it go. ; )
Elite Force is perhaps a good analogy to this game, since it too (again going by reviews here since I haven't played the full game of RC yet) had GREAT, but short single player, and "tacked on" multiplayer. Of course there was no console version of EF (that I know of).
