I'd probably go with Mario Kart so far but it's hard to pick between it and Tropical Freeze. I haven't played Shovel Knight yet but I hear it's awesome. I'm sure Bayonetta 2 will be good and I'm really looking forward to Captain Toad as well. And Smash, well, I know it'll kick ass.
WiiU sure does have some epic quality games throughout 2014, droughts be damned.
EDIT: Sorry, Curl... I didn't specify why, lol. I'd go with Kart because I love the series and I think the WiiU version has the best selection of new tracks of any entry. Outstanding production values as well. For people who prefer Smash over Kart though, I can understand why that would be their choice because it looks like a fan's dream entry as well.
