6/10 for me.
Solid but unspectacular. More information on things I was already getting (Splatoon, Mewtwo DLC, Box Boy, Affordable Space Adventures), convinced I want a couple more things either new or previously announced (Lucas, Fatal Frame, DK64, 200cc mode); remain unconvinced by Puzzles v Dragons, Code Name: STEAM.
Dissappointed by: the card driven Animal Crossing spin off; another Pokemon spin off with microtransactions; Mario Maker being September; Fire Emblem: If being 2016 for Europe; no date for SMTxFE.
All in all I'm hoping Nintendo are saving some major stuff for E3, both for Wii U and 3DS. Still happy I have the systems, but I can understand why sales are slowing for 3DS and Wii U continuing to struggle.
