If you're getting into the nitty-gritty, you may want to think twice about buying this game. If you're looking for a real challenge, then you'll be disappointed in this game. Voice acting a great tool, but only when used correctly and effectively. And plots shouldn't be explained between each character, they already know what's going on. And if you don't want to play a plot that's already been used, then Gears 2 is not your game.
If you buy this game expecting the crème de la crème, a top notch game that is 2 steps above the rest, then you're in for a rude awakening. This is a classic example that newer games aren't better just because they are new.
