I disagree. I buy games for the graphics. Consoles can't do 144Hz (FPS) like my rig or many people's 120Hz. And that's one thing that is important to me, especially in shooters. And most people say when you play on 120+, you can easily tell going back to 60. But that argument aside even, PCs are capable of doing a lot MORE (AA, etc.) then the decade old consoles who refuse to update because 'they still sell'. So it still looks better on the PC while keeping smoother graphics. And games (like Skyrim) are intentionally nerfed to keep them smooth on the consoles in the graphics department (and some games in other areas also). But again, that's ANOTHER topic.
As for the modding, that's another PC feature I LOVE. I played Oblivion forever because of the cool mods I could do. I still play Baulder's Gate 2 because of the new mods and levels people create are so intelligent and sometimes shockingly well done. Manufacturers should really be looking to the best of these people and offering them jobs, at least contracts, for another installment.
As for Rage, I never bought it because the reviewers that I actually trust all gave it bad reviews. If none of them liked it, I don't need to look at it. (and some of my friends that did buy it, I heard their complaints of texture pop-in problems, etc. as well as a pretty stale story or something to that effect. It's been a year...) But now that it's got a mod pack coming out, I might pick it up then. So in that situation, they might get a customer they otherwise never would have had. So that could be a very good thing for them. But I do agree, it should have come out since the start. Then they might have had a customer at the original price, or shortly after, instead of the now almost give-away price.
