I dont know what it is, i mean it beat out my other favorite games (burnout 3, halo 2, kotor 2, etc) and I think that it may have to do with the price (20 bucks), the depth (300+ skills to earn/sort/use/kickpeoplesasswith), and the multiplayer (online battles are adrenaline filled, tactical and action packed).

Sure the game's visual style is kinda goofy, but after you find out the monster plot twist it becomes a little more tolerable. I can only hope that PD2 will have customizable characters. hopefully MS sees that this game is selling pretty well and that it is pretty popular. Hell they need more niche products and they have something that works, why not stick with it and make it more awesomer (not a word).

Customizing aresenals is great, and if you make some friends online they will usually help you create strategies and techniques. They dont give their stuff away, but they will share secrets. Some of my best online experiences has been matches where i get a real team player of a teammate and we work together to dish out some tactical damage.

oh yeah, so if you're still on the fence about this game. GET THE HELL OFF IT. it has been a gaming experience unlike anything else I have ever played. It has the depth, the fun, and the multiplayer (and a great campaign too) to make it worth the measly twenty bucks you'd spend.

In fact here is a picture of a twenty dollar bill, something that you can part with for this awesome game that most likely be hard to find very soon.
