This is the top 10 games I have played the longest, according to Xfire

Battlefield 2142 -- 134 Hours
The Elder Scrolls IV: Oblvion -- 51 Hours
Garrys Mod -- 31 Hours
Trackmania Nations Forever -- 25 Hours
Spider Solitare -- 15 Hours
Gears of War -- 13 Hours
Portal -- 12 Hours
Half-Life 2 -- 11 Hours
Peggle Extreme -- 9 Hours
Audiosurf -- 9 Hours

BTW the reason why it says United States on my Xbox Gamertag is because I accidently registered Xbox Live under xbox.com/en-US not xbox.com/en-AU and there is no possible way of changing it :cry: Luckily it is only for one month but if I do get Xbox Live in the future, it will have to be under a name other than Superironic :(
