I tried to play SubNautica for a bit (after playing some Minecraft) but they put their waiting loop in "the wrong place" ... in Minecraft you have to wait to "retrieve the items" (ie: mine 100 stone blocks), while in Subnautica you had to wait to "combine the items", ie: staring at a boring progress bar while trying to craft some rubber suit fins or whatever. It seemed like it was going to turn into a "stare at the progress bar to build things" game and that really turned me off from sticking with it.
