>ITT Shit habits that hinder your enjoyment of a game, but you always do anyway.
For me every first playthrough of a stealth game turns into a save scumming nonlethal grindfest. I need the golden ending first.
Another first playthrough annoyance is making my create a character into a self insert power fantasy. It's boring, but in every game outside Mass Effect I did it.
My final one is pretty common. Hoarding resources for so long, I end the game without ever using them. Jak 3 was the worst for this reason. I only ever used the weakest yellow gun and never changed top light or dark mode because I thought I world need it later.
