Ah, Dark Souls! I'm a huge fan of the first one. Splendid atmosphere and soundtrack. I own a digital copy on Steam. I've even participated in the Re-Kindling event arranged by Reddit.
I don't have the first one, although I beat it like 15 times on the xbox (Ng+4 on account and then just a bunch of NG+ ones) I do have the 2nd and 3rd one though, but I can barely run the third xP
I've played the third on my cousin's PS4. I don't like the overall demeanour adopted by the new characters. Everybody's either too sorrowful or too pessimistic. In all honesty, Dark Souls 1 was much more balanced in this regard.
