If you follow the game the way it wants you to, it won't even feel like a game from the series. You will find yourself in a buggy capture-the-flag setting, flavored with DOTA-like enemy respawn cicles and really annoying quest-update spam. It becomes less annoying if you refuse to be kept busy with the faction wars and just play your own game. In this case I'd recommend it to die-hard fans ... but skipping it is no big mistake either.
I really enjoyed the twisted story and it's original presentation. But there were some downsides to much for a 5/5-rating: - The controls. You move your character by letting him follow your cursor. Would be okay if he wasn't so terrible slow and got stuck at every edge. - The voices. Some of them are nice, but some of them are a little too cartoonish. Aditionally, the protagonist's voice seemed a bit inappropriate to me... - The puzzles. A bit to many end up in pixel-hunting, which is even more annoying when combined with the contols-issue. Apart from that I really recommend this game. Maybe you should keep a walkthrough at hand for some situations. The game is not about its puzzles, it's about its plot. It would be a pitty to miss the whole experience the game offers just because of some weaknesses in the gameplay.
