You'll cry from happiness.
And the gameplay, I mean, WOW. No I mean, really, it feels like I'm playing World of Warcraft. Everytime I start up a new game I imagine in my mind, "YES! Level 42 Dark Elf Mage, here I come!". And I mean, the choices are endless. Sort of. Up to 26 cases, anyway. But you'll have so much fun roleplaying in the magical world of NBC's demon lovechild you'd forget all about the multiplayer!
Nothing beats pwning n00bs at Deal or No Deal. Crushing the hopes of new players in Deal or No Deal is like nothing before! Instead of typing into a clunky old keyboard, I merely yell at them through my DS and throw it onto the floor! Occasionally I even stamp on it a bit and headbutt my cat, but hey; I have a competitive nature! And I'm sure you will too after playing at least 70 hours a day!
