Mario Kart 8 on the Wii U.
Hmmm. I must confess I'm not sold on all the hype. It certainly is a beautiful game - certainly on par with most of what the PS4 has to offer barring the resolution difference (which I can rightfully claim, as I have a PS4 running on the same TV). And it plays well enough, and is pretty much everything that you'd expect from a Mario Kart game. Some of the new tracks - Mario Stadium in particular - are pretty good. The problem is that the game is not much of a revolution/revelation over Mario Kart 7 on the 3DS, the same old game structure time and time again is getting a little tired. Also, the flame hopping exploit is being abused left, right and centre online, so playing online is no fun anymore (although I do enjoy playing against my gf, and local is where MK is best played anyway).
MK8's bigger problem though is the atrocious weapon balancing and the AI rubberbanding, which hasn't been so bad since Double Dash on the GameCube. The weapons distribution essentially forces upon you coin after useless coin, yet the AI manages to bombard you incessantly with shell after shell after shell. Also, I really think it's high time Nintendo got rid of that fucking blue shell.
Also playing Watch_Dogs on the PS4. Decent looking game, rather enjoying everything it has to offer right now, but somehow I can't escape the feeling that it plays exactly like Assassin's Creed, but with guns. I mean, Aiden Pearce even runs like Altair from the first game. Also, the online integration is annoying as fuck - you can switch it off, but that automatically excludes you from quite a few of the unlocks.
