Yet it has more stealth gameplay than every metal gear solid game combined
Outside of the camera positioning I can't think of one thing that SC has *more* of than Metal Gear. In fact most Metal Gear haters immediately cite the Camera as the number 1 reason why they can't stand the game.
I still maintain that they're completely different genres now. One is a pure sneaking game and the other is an interactive action movie.
MGS3 turns the series into a action hero simulator pretty much, where you're largely free to choose how you want to proceed with the mission so long as you're able to get things done and deal with the consequences. It's truly tactical espionage action now, and not "just" a pure sneaker or so as the title put it.
With Splinter Cell however I can't shake that feeling that you're being lead along on a VERY tight leash. While you're still given *some* freedom to elbow a guy in the face repeatedly at the end of the day you're still put on a largely confined path.
The single player game so far has been largely the same with some very minor improvements (and to some extent, SC

T introduced a play mechanic that effectively broke the single player experience). Really I think at one point they can just ditch the single player Splinter Cell game completely and just focus on the multi player and no one would care at all.
At this point I couldn't care less about what happens in SC:CT story (beat the game, save the world, good job!), I just want to see how they've cleaned up the multi-player game, and how they've implemented coop. whereas MG was pretty much the exact opposite, where I'm motivated to play to because I absolutely have to see what happens next.
