Well, I grabbed this game, and so far I really like it.
I've played two other Splinter Cell games, and while I liked the idea, I got bored with the execution. I think my biggest complaint with those is that you're just sneaking around doing stuff and the goal is to avoid enemies. I don't get the option to remove all threats in sight because you simply can't do that in certain situations. Also, it was complicated to figure out if you were detectable or not.
Conviction doesn't have these problems. The goal from the very beginning is vengeance. You're there to kill people, and to eliminate every threat. In some cases, you don't have to, but it's very satisfying when you keep headshotting these guys with a silencer, and everybody thinks you're a fucking ghost, ninja, or Batman. In fact, it reminds me a lot like the last Batman game, except with guns and Sam Fisher isn't tying these guys up.
The greyscale detection system is great, even if you're playing a good portion of the game in black and white. The wall-based direction is also great and original, adding a bit of art to the storyline. I love that you hit the Back button and it displays your objective as a light object on the nearest wall or floor you're pointing at. They've made an effort to strip down the interface to make it less complicated and it works well.
I'll will probably complete this game, unlike the last two SC games I've played.
Rosalina: But you didn't.
Robert: But I DON'T.
Rosalina: You sure that's right?
Robert: I was going to HAVE told you they'd come?
Rosalina: No.
Robert: The subjunctive?
Rosalina: That's not the subjunctive.
Robert: I don't think the syntax has been invented yet.
Rosalina: It would have had to have had been.
Robert: Had to have...had...been? That can't be right.
