The old cliche holds true here -- if you loved the first, you'll love the second. But just beware of what you ask for. SF2 is more of the same, greater levels, more simplistic story, more trial-and-error gameplay. And despite all of those problems, the game is still near great. The two-player mode, in my mind, is a killer addition, and is equal, if not better, than the deathmatch levels in Medal of Honor.
My biggest disappointment with SF2 is that once I reached the ninth level, I simply didn't care to finish the game (of course I did finish it). But I was dulled by repetition, and while I wish I weren't, it happened. So, would I would buy the game? Absolutely. It satisfies that primal videogame urge to sneak around and snipe enemies, or to simply blow them away. It's still a great action game.
