Buying borderlands on friday, see you there?
Could always spend the coupon on MW2, then burn it on the news as a protest ( of course removing the disc, lets not go over the top here)
Don't get Battlefield 2.
EA just release the booster packs for free about 2 months ago so you would be buying something you could get for free. You would just have to buy the standard game.
If you do get it there are some great mods available.
Ordered BF:2 and Mass Effect this morning on Steam, then tried the Left 4 Dead 2 demo. Which leads me to the conclusion that I need to get Left 4 Dead 1 from gamestop. I sue wish this was a coupon for Steam instead of Gamestop though.
