Squeenix's was disappointing mostly because they already blew their load at the console manufacturer's presentations (Tomb Raider looks amazing, Hitman, FF7 Remake, World of FF).
Nintendo was a disaster. A couple of the things they showed looked interesting (Paper Mario & Luigi, Star Fox looks like a pretty version of Star Fox, Mario Maker has the potential to be awesome if they don't fuck up the sharing aspect of it) but they announced fuck-all for the Wii U (guess they're just going to let it ride off in to the sunset) and the 3DS is mostly getting ports and weird knock-offs. Personally, I wrote off Nintendo 20 years ago. Not because of childish animosity or "durr hurr Nintendo is for babies". They just weren't making games that I was interested in anymore on console, they began making their consoles difficult or damn near impossible for 3rd party publishers to port their big games to (making the chance of them getting anything remotely interesting from 3rd party publishers similarly impossible) and handhelds always gave me eye strain and headaches. They did fine without me and there's always someone turning 10 every year that will be enchanted by what Nintendo does better than anyone else (crafting family-friendly, mechanically sound games starring memorable characters) but that press conference has me wondering if Nintendo even understands what it does well anymore.
