I saw you on the other night, so I am assuming you picked it up.

Yeah, I had to throttle back some of the graphics settings while playing on my Xbox One X, but once I did it ran just fine, both campaign and MP. Now that I switched to the XBox Series X (I will never get over how bad the naming system is) it has been running even better.
Some big changes are coming to the Infinite store this week and a new free "event" battlepass is starting today too, with some neat looking cyberpunk like cosmetics. Based on user feedback, 343 is also going to be trying out some new (lower) pricing for store items and will breaking up some packages and allowing users to purchase single items, without buying the whole package. They have some other plans too for future store and unlock improvements. I think it is very promising to see them actually listening and responding to user feedback, and being transparent about it. It gives me a lot of hope for the future of the game.
On a sad Halo note, all the original XBox360 Matchmaking and Online servers went down forever last week. The games are still playable in MCC of course, but the original experiences are no longer available. I played a few final games of Halo 3 to send it out last week. It was bittersweet, I had so many good memories on the old servers but it was good to see them one last time.
