Well, as a whole probably Tekken 7, although nothing will beat Woshige standing up in Xrd top 8. Nice to see Naps at least getting into the top 8, considering he as an American at best played an old build during another tournament.
But honestly... I didn't really watch anything else. I caught a bit of Catherine (because someone on IRC mentioned one of the contestants had a Chihaya t-shirt), which was interesting, and a few final games of Mortal Kombat X, which was boring as hell (literally only watched it because Aris was commentating). Other games don't really interest me, so I just watched a musicmaking stream. Wish there was VF5. ;_;
And speaking of iM@S, there actually is an 765pro "team", which is why you've seen people with idol t-shirts. Saw that one guy during Catherine, but according to Twitter there were others as well.
