I wasn't there to present anything, but it was a bunch of fun. Played Splatoon at the nintendo booth, saw some cosplayers, tried out nuclear throne, played a level of the Shovel Knight DLC. The thing I did the most was the challenge mode at the Hyper Light Drifter booth (and I got the highest score: https://twitter.com/GIRakaCHEEZER/status/638479147266785280 ). The story demo they had also looked pretty good.
