Actually, my 360 worked just fine. I did call and say I was getting sporadic errors just because I wanted a perfectly good working condition 360 for when Halo comes out and sent it in.
Rhymes, I agree in a way. It is just an FPS, but what was revolutionary about the first one is that it is the first console FPS that really nailed the control scheme. It also is the most realistic in that you cant carry around a bazillion weapons and unlimited ammo. You are limited to two weapons and 6 or so grenades (I believe you can carry more grenades in 3, but not sure). It was the setting, the story, and the fact that you had to think about getting past that group of bad guys instead of just balls to the wall murder death kill.
But really, it is just another FPS. The story rocks IMO and what drew me in. From the very first level in CE all the way to the disheartening ending of 2. That and Master Chief ****s Mario's and Link's all day long. Oh and the first time you encountered the Flood, scary stuff. Reminiscient of the first time you played parts of Resident Evil 1. Good drama. Good sound, great flow to the game. Sometimes repetitive in the later levels of both 1 and 2, but still a great game.
Conversely, I thought MGS was ****. I think it might be the most overrated game ever. 1 playthrough, game sucks after that. Bioshock was gorgeous but has very little replayability. I might play 1 more time (that is, if I can be bothered removing the Halo 3 disc) and never touch the game again.
