I know this is an enthusiast Gaming forum, but some people's lists are... LONG. Dayum.
If this is list of games I'm buying in 2015 that came out in any year (as opposed to games that come out in 2015 exclusively):
Uncharted 4
Zelda U (and by extension, almost any Nintendo first party offering that's coming out in 2015)
REmake, of course. If PC is 60fps, I'll go for that, but for the time being I'm considering PS4.
Assassin's Creed Rogue (PC)
Assassin's Creed Unity (yes, that Unity. At the end of the day, I'm still a fan of the AC series.)
Batman: Arkham Knight
Shadow of Mordor (if I don't buy it between now and the end of the year)
That's it for now. I'm still playing catch up with a lot of older titles, so no reason to hurry out there and start buying stuff.
