I think it was a great conference and I can imagine it being even better for Japanese gamers or others preferring Japanese games. The list below was the best case scenario for me so I'm pretty satisfied (even got an unlikely surprise in the form of Dragon Quest). A little peak of Final Fantasy XV or Type-0 would've been great though.

Bloodborne

Dynasty Warriors 8: Empires
Final Fantasy Type-0 HD
Hyperdimension Neptunia VII
