A GTA-style RPG, Where You Play as Evil or Good.
Following along the lines of Black & White, the user makes choices that are either good or bad, and this reflects onto your character by turning him into a horny* devil or a holy angel. While not all of the decisions are good/evil, most of them are. I can't really say what any of the decisions are without spoiling the plot, but a few of them are interesting dilemnas. (Since choosing Good usually ends with sappy results that don't help your character, I'd recommend Evil. You'll get more interesting story.)
*Horny; something that has horns.
There are a couple of problems with this game: -It's very easy to finish. Both in difficulty and hours spent playing.
-Oh my god, what the hell kind-of Map system is this!? It's like trying to read a book while Jackie Chan is trying to kick it out of your hands.
-Some of the characters are downright annoying. (Get used to hearing "Try and get your combat multiplier up." a LOT of times. Or "You've recieved a new quest card!")
-I know there are a lot of sidequests, but it feels like there should've been more. At least 20 or 30 more.
-The ending brought up more questions than answers.
-Some of the cutscenes felt vague, and I figured it would all be explained later, but no.
-(This is a minor problem), but every now and then the AI craps out and the enemy stands completely still indefinitely, making the fight not very challenging.
**Notes about the Expansion**
It's alright for an expansion, even though I thought it was just part of the game. Most of the enemies you fight are the same, only painted white because it's snowy. The terrain is also painted white. The Quest where you have to kill or save some Prophets is fun, but the rest of the expansion is basically the same as the rest of the game. I found the expansion last boss less of a challenge than the regular last boss. I would've liked it if the zombie Scythe was fleshed-out* a bit; he seemed like an interesting character, but he never got a chance to fight or do anything cool. Actually, the first time I played he was the only character left standing. (See next paragraph for details.)
*Figuratively.
But hands-down, I like the 'kill everyone' scenario the expansion pack offers. You're given the option to kill all 3 of the most annoying characters, one-by-one. Given the fact that you've already killed Whisper, that's basically every jerk in the game.
