I've got to get myself the id Super Pack someday. I already own all of their games, but I'll gladly pay them a second time for their pivotal role in the gaming industry.
EDIT: That's when I remember that I also want Civilization V. And New Vegas. And that I'm an unemployed student.
I hear that many people have had problems running certain mods on Steam Oblivion. For that price, though, who cares? If I didn't already have three copies I'd be all over this.
