I've kept out of the MW2 discussions so far, since I didn't feel like jumping into that shark-infested pool of hate. I was gonna give IW the benefit of the doubt (and I still am), since for me MP is an interesting extra, not necessarily an integral component of the game - if it was SP-only, I'd buy it anyway.
That said, I'm starting to get pretty pissed off myself.
I pre-purchased the game on Steam about two and a half weeks ago, for the full ?60, expecting to be able to download and play it on the 10th. This was before I knew about the controversy. Then I started seeing more and more "IW is screwing you over!" threads here on TE, with more and more talk about the PC version having gimped MP. But like I said, MP is an additional bonus for me, not a primary requirement, so I let it slide.
Then I hear about stores selling it for about half as much as I paid for it, before the release date.
And now this bullshit.
I'll still give IW the benefit of the doubt when it comes to the SP campaign, but really, I'm starting to believe the conspiracy theories about IW/Activision gimping the PC release on purpose.
The SP campaign had better be pretty damn good.
