I wrote off buying Driveclub when they confirmed 30fps, so it being a disaster isn't a personal source of any woe.
This is only the second AssCreed I'm skipping (Revelations being the first), despite thinking most of the games are crap. I was very excited when they announced Paris. Shy of London or an Eastern setting, Paris was always near the top of my list of locations I was hoping they'd visit. I was already not planning to buy it before the parity stuff, by the time the final quality was established, I was long passed tempted by it.
I don't have an XBO, but I wouldn't have bought the MCC anyway. 3 is the only one I'd care about replaying, but I think people are kind of overestimating the issues with the package. There's a pretty good chance DC will never be fixed really, certainly the + version could very well never happen. The MCC will be fixed, MS can't not do it.
I was very excited for Destiny, I even loved the Alpha, I'm not entire sure why I skipped it, certainly the reception on GAF hurt it, but also working and a couple of friends not getting it when they had also planned to.
I get why the thread is two separate face offs, so to speak, but I would have to say Destiny is the biggest disappointment of the four, because it's the only one I actually expected to buy and enjoy until very shortly before its release.
As an aside, Drakengard 3 and Ground Zeroes were my actual biggest disappointments this year.
