I got bored of AC4 I think. The pirate stuff is fun there just isn't enough of it for me. As in, the game doesn't revolve around being a pirate, there are only a couple of game systems in place that take advantage of it. Obviously this isn't meant to be a pirate simulator, but that's what I want dammit!
I'm liking Garden Warfare a lot still, the only issue being that the peashooter is an OP class. Luckily there is an upgrade system in place that makes it where people want to use multiple different classes so that the lobby isn't full of them.
I might start playing Pikmin 3 again as well, an amazing game that has so much replay value it's insane. I've beaten it 4-5 times since launch (last August), I love playing it. Best game on Wii U currently, IMO.
