Yeah, I'm probably going to get this game with my $20 GS gift card from Reach, even though all of the preorder bonuses for the game are pretty much useless. lol

Hardcore mode sounds awesome. It sounds like they're adding some of the older Fallout 1 and 2 flavor to the Fallout 3 engine, which will be amazing.

It will be cool to create different ammo and other things I bet they have some pretty rare stuff to create.
