The problem is if I made rubbish decisions early on I can wriggle out of them too easily. I rather like having an excuse to use obscene language at the computer screen
for a while before going back and starting again.
then do it. swear cuz you've made a mistake and throw a keyboard at the wall. but it will not change anything. the game is not random. all enemies are pre-placed. so you'll either use a mirror and save a lot of time to fix a mistake. of you'll load a save at the time before the mistake and fix it. and then you'll waste a lot of time by going through the game to the moment where you've stopped.
even completing act1 can be boring sometimes if you've done literally everything in the act... I guess during my playthroughs I've chosen every dialogue option possible
same with a honor mode. you can complete is without ever using a mirror by having a plan before the game.
