when GOW came out, it had the best graphics period. i think it still has the record for most copies sold unless bioshock beat it. GOW is better because you can play the campaign online with no lag. COD 4 is better because the graphics are realistic, AI's are brilliant and eventho there's not that much levels, you will break a sweat playing it on hard. i would say.. get COD 4. and this is coming from a die-hard GOW fan

do the following steps:

1. access your xbox 360 guide

2. select your profile (click your gamertag)

3. select "auto sign-in"(sixth option)

and there you will have the option to enable or disable auto sign-in for xbox live and msn
