Xbox One Thoughts:
Short answer - fun, but needs more games.
Slightly Longer Answer - I ended up getting it launch day. Got Ryse, BF4, and NFS Rivals. I'm pretty happy with my picks.
Ryse -- What a gorgeous game. I'd be hard pressed to find another game that looks this good at this time. The gameplay is ok, i'm partial with hack n slashers so I've been enjoying it. Just make sure its in small doses otherwise you'll get sick of it in a minute. It's definitely a game to show off to your friends, though.
Battlefield 4 -- More of the same as BF3 but with a few more choices and 60fps for consoles, FINALLY. Been having a ball with this one. The campaign is pretty meh but the multiplayer is where its at. Highly recommend it.
Need for Speed: Rivals -- Game is pretty, arcadey, and loads of fun. Definitely the surprise of the bunch. Just cops and racers duking it out on the road. It's basically a fast paced driving only of GTA5. The way this game does the multiplayer is pretty ingenious. Just drive up to some car and LB and bam you are in a race. quick and easy.
Killer Instinct -- Haven't really played much, but its a fighter. it does have a nostalgia factor to it. Will definitely play more later.
Kinect Sports Rivals -- Surprisingly receptive with the kinect. I'm looking forward to playing this one with my daughter.
All in all, i'm pretty stoked with it. After work tonight, I'm going back on and racing some more dudes.
