I checked a few videos on the game and the first thing that stuck out is Oblivion tier NPCs. Their movements, replies and actions are incredibly bad for a game released this year, and as usual we will soon have thousands of 'dumb AI' memes all over the internet from it. Also no swimming animations in water and the usual 'look under the water / over the water' glitching graphics, or if there is actual swimming its completely bugged. I'm optimistic in getting another 'NPC bugged into swimming action while on a ship' meme like TES games had.
Also you fast travel between planets, from what I saw there doesn't actually be an option to fly around all the space like in No Man's Sky and such games.
The planets are 'left empty by design' to make the game feel more vast like space should be? But thats completely ruined by just fast travelling everywhere.
