As someone with almost 500h in NMS, get in fully aware that things get repetitive fast. Once you get off planet and can visit other stars the first time, it’ll likely take 2 hours to see all different kinds of planets.
Unlocking (“learning”) the 3 aliens’ languages is the absolute worst slog in the whole game.
Another ultra tedious chore is doing the daily missions for Quicksilver (special currency) to unlock some nifty cosmetics.
Also, combat sucks. It just plain sucks. The most annoying thing to me is: if you don’t fire your weapon for 1 or 2 seconds, your dude will put it down, which will create a small time window where you’ll have a significant delay between pressing the fire button and actually firing, because of the animation.
