Well, if it's Demon's Souls you're wanting to play too, I could definitely make a wager: I bet you die during the tutorial.
I liked how Dark Souls was pretty much open world in a sense, but I didn't die nearly enough as many time as I did in Demon's Souls, although I got scared at some parts... as in, y'know, literally scared... I think the reason I didn't die as much is because I'd already played Demon's Souls beforehand, so knew what to expect when it came to fighting enemies and the boss strategies, even though some were completely different.
Yeah, you should really pick the game(s) up, they're fun and hard at the same time, and if one of them is going to be on the EU Playstation Plus, that'd be great!
I died a ton on demon souls the first time I had it, but that was because I accidentally picked Barbarian /deprived. I then play Dark souls and man that game was easy comparatively. I went back to play demon souls again this time as a royal and it was just as easy.
