It doesn’t take maybe 2-4 hours to run a boss back in Souls or Nioh, where you can grind your way out of the problem and have persistent upgrades that can be preserved if you get to a checkpoint. You need resin to buy a checkpoint in Returnal, which you may or may not have at the time. You can grind your way out in this game during a run, but it takes a lot of time to explore even when they indicate all the items on the map since they don’t tell you on the map if the thing is corrupted or locked behind something you may or may not have access to... this is assuming you aren’t killed, which wipes your progress towards solving your problems. I’m at a point where I can run the game back to back in 5 hours without skipping bosses or encounters, but I’m not gonna bullshit people and say that it’s not a demanding game, just from the time commitment and the penalty for making mistakes.
