I just started Dark Souls 1, it's been a game I knew I would love the setting (pure medievalesque, undead, demons) but had avoided because I play games to relax rather than get angry. This is for sure not a relaxing game! You need to tiptoe around, enemies give no quarter, bosses need to be understood before they can be beaten, and as you say you can lose your "money" very easily. The lack of saving or pausing is a pain, and the fact every enemy respawns at rest is also very annoying!
But, BUT it a damn good game, damn it!
I want to play Divinity Original Sin 2, it's in fact a game I attempted twice so far, the first time it took me about 1 hour to give up in disgust, the second time I gave it a few days of my time only to get hopelessly stuck in a maze, party separated, characters dead with no clear idea of how to revive them. The only reason I want to go back at it is because a couple of gamer friends whose opinions I really trust have said for years that it is "the greatest RPG ever made". Polar opposite to Dark Souls though, the whole game is one big pause, and needs careful planning, observing and strategic thinking.
