I saw Nintendo and MS's conferences.
Nintendo had the best E3 since Switch was released, but at the same time, for it's 3rd year it was a let down. The only major new game was… a sequel; the biggest 3rd party game was a port.
I was told again and again to give it time for the support from both Nintendo and 3rd parties to increase. But so far, on the 3rd party front, theres' nothing to see. And on Nintendo's side, i'm not seeing anything special either, be it on quantity or new IPs.
If they have new IPs, why show Zelda BOTW2 instead of one or two more?
MS, on the other hand, had a really good and engaging conference. Really liked it!
MS really showed that they are putting a lot more effort for their consumers.
