Playing on Ultra Violence without quicksaves has been my peak Doom experience so far. Losing your entire arsenal sans pistol HURTS, but it's a good pain. The few times I did die proved to always be recoverable and further reveals how well designed the stages are. I was always within reach of enough ammo and new weapons to crack the soft-puzzles of the later episode's encounter design.

I highly recommend giving Doom a spin with the resolve to not crutch upon save-scumming. At least eventually.
