Halo 2 is just simply the second best first-person game to date. It doesn't really live up to Halo though.Worth playing.
The graphics are sweet, but it's not the best you will see for the Xbox. I wish that that they would worked a little harder for the game for glitches, and such. If you think about it, two years of making a spetacular game isn't enough.
The gameplay is nice, and is as silky as it can be. Moving around is just like slicing butter with a knife. Dualing and just having one weapon is balanced out, and has a fair deal. Sniping, melee, and lag is out of the resort of fun although. Sniping is so easy, it will make you quit. Melee is very glitchy when you play online or offline. And lag will get your frustration going.
The sounds are just simply amazing. Somtimes it won't get that War World II sound in your blood though.
The replay value is quite good for some Halo fans. I played it for 2 years, and is quite bored with it. If you have an Xbox 360 like me, get Oblivion. That game will make you play forever!
