Starfield for me.
I really enjoyed my time with it, and put 260-ish hours in, so it seems weird to call disappointing. However, I expected thousands mainly through base building like I did with Fallout 4, even vanilla.
I really liked the main story. It's best one (main) they've ever done (until the end), had me so intrigued, especially the NG+ promise, but it wound up ending in a lackluster fashion. I hope the shattered space DLC does more with it, and give us the Va'ruun faction. They really need a faction with some teeth, as everything is so PG. One of the worst parts are all the ugly NPC's, the game has next to no sex appeal.
There's a lot of Bethesda magic in the game, but the way it's scattered in pockets takes a lot away from it. It didn't help that so many quests were half baked, and or could have been handled with an email instead of forcing us to into several loading screens.
Fast traveling isn't always as bad as everyone makes it out to be, because you can do much of it from your cockpit and not enter menus, but the lack of exploration in ships is the biggest fail for me. All that space between planets and they did nothing with it.
Ship designing is really fun though, where I spent most of my time, but it has a ton of issues. Improving this and adding explorable areas in space is something they can easily implement, especially the former.
Anyway, I can babble on and on about what the game needs, but I'm sure anyone who has played knows what I'm talking about.
