Trine 2
Trine 1 in coop is one of the funnest games in existence. Nothing whatsoever indicates to me that Trine 2 could be anything but another stellar game.
Skyrim
Always loved the Nords in Elder Scrolls games. Bloodmoon, the expansion with the icy island of Solstheim was my favorite part in Morrowind. So even if worst comes to worse and Skyrim turns out to be a shallow mixture of Oblivion and, say, Fable, I'm probably still going to enjoy it.
GTA V
Haven't seen a bad GTA yet, even if I enjoyed some more than others. I haven't even finished GTA IV because I just didn't care about the story anymore at some point, but I still don't really feel disappointed with the game. Had a good time with it, and the radio stations alone typically make these games worth playing so... Also, the trailer was one of the best and most honest trailers (games or movies) of recent times too.
Halo Anniversary Edition
It's a remake of Halo: Combat Evolved with graphics that are, I'd say, comparable to Reach. It looks nice and it's interesting that you can switch to classic graphics in real-time at the press of a button, but I care more about getting to play Halo 1 again than about the facelift, tbh. It's backwardscompatible, but my Pal50 version doesn't work with my 60Hz monitor and I'm certainly not going to bother hooking up an old TV to play the game again. If this Anniversary Edition is reasonably priced I'm going to go that route instead.
Prey 2
I know next to nothing about this game, but the CGI trailer with the (overused, for a short period of time) Johnny Cash song was so incredibly bad-*** I can't help but feel a little excited. Prey 1 really dropped off fast after the glorious beginning, but it still has that going for it and if the CGI trailer and that ancient bit of news about Prey 2 is anything to go by and we basically get to play a bounty hunter in a completely alien open world that would really be something...
In Country: Vietnam
If they can deliver a credible but fun Vietnam experience, if they can succeed where so many Flashpoint and ArmA mods have failed, that'd be great.
Far Cry 3
I probably wouldn't have looked at it twice if Farcry 2 hadn't been such a pleasant surprise. I'm still going to wait for more info, and maybe a demo, but I'm still looking forward to this.
In that order.
