In terms of excitement:
#1 - Xenoblade Chronicles X - And honestly, this is probably the most hyped I have ever been for a game before. Warcraft 3 and Starcraft 2 comes close.
#2 - The Legend of Zelda - Big shocker there, looks amazing, new zelda game, new zelda game....
#3 - Star Fox - Cant wait to do some barrel roles. As
#4 - Splatoon - Looks so much fun, hopefully it will be a hit.. not sure how the community would enjoy a different non generic shooter.. how weird that sounds.
#5 - Captain Toad: Treasure Tracker - Yup, I live in Europe. A game that I will surely enjoy, love puzzle games =)
#6 - Mario Party 10 - What can I say, a sucker for party games hehe
#7 - Yoshi's Wooly World - Looks cute.. think I will enjoy it
#8 - Mario Maker - I dont like doing maps etc and I am not sure if you are able to download other more creative players creations. If so, it will most certainly be great fun and would likely rise a bit on the excitement scale.
#9 - Kirby and the Rainbow Curse - Never really a fan of Kirby... let's see how it pans out.
#10 - Devil's Third - Havnt seen much of it yet, and the little I have seen didnt impress me much. I will wait and see what happens.. likely not buying but if it gets great reviews I might reconsider
I will probably end up with 8 of these, great year for me!
