I think it was a solid 7.5/10 show. Lots of new announcements and games coming to Game Pass that I definitively want to play. But I still think it would have been a blow out if we would have seen just a bigger gameplay demo of just 2 of the many exclusives they have announced (any combo of either Avowed, Hellblade, Perfect Dark or Fable) would have elevated it to 10/10.
i think one issue is that they do not want to recreate another 2020 Halo: Infinite reveal, where they show gameplay for a game that is definitively playable, but lacks in polish.
To be fair it seems most studios are like this nowadays. After the Cyberpunk 2077 fiasco, I don't recall there are that many devs that are showing gameplay for games that are more than 1 year out. When they do show gameplay reveals, it is often just uploaded online when it is ready.
Also, I do expect they'll be another Xbox event this year, for the 20th anniversary of Xbox/Halo, where they'll show more Halo and confirm a release date.
