The worst one was the Nier Automata tutorial. You had to play this non stop for about an hour with no saves.
Not only is it an unskippable tutorial, it's a goddamn driving test, and was impassible altogether unless you pulled off some poorly-detected stunt move you'll never need to use.
I've only ever managed to get past it once, despite repeat attempts.
Like c'mon, I get there was a lore explanation behind saves but c'monnnnnn
