Inventory management is very much an early game gripe. Get 10-15 hours in and it's not really a problem anymore. It's part of the game's progression, IMO.
That reddit thread is silly and expected since the week before launch when that whole subreddit lost it's mind over AMG BROKEN PROMISES!
I read/watched a lot of shit in the buildup to release of the game, so perhaps a bit fanboyish, but the only gripe I have is that the universe is obviously not as big as they had claimed, for whatever reason. If it was, there should never have been an opportunity to meet someone else. Since the dev was claiming all along that it would be "next to impossible" to meet another person in this universe, i had literal zero expectation that there would be network code of any kind other than a database connection. I always expected a solo exploration game, and that's what I got. I'm still only 15 hours in though, so we'll see how it goes! I got my new ship and loads of inventory space at least!
