I've never heard of those games before. But I guess in that era I was pretty mainstream, all I played was pro evo and gran turismo on the ps2.
My impressions are From made pretty niche games, bloodborne must be the most mainstream game they've made right? That's not to say that they've set out to make a mainstream game, but I mean Bloodborne is the most well known game they've made.
Demon souls, dark souls etc weren't really hyped or advertised as much as Bloodborne has been. I mean I saw a playstation advert on TV the other day about bloodborne, I had never seen dark souls advertised like that.
Fom what I read demon and dark souls were very good games last gen, yet they weren't mentioned as much or even considered for goty etc, yet bloodborne is hyped.
Even in local gaming stores there was plenty of point of sale stuff from Bloodborne, there was NEVER any of that for demon souls, dark souls etc, they seemed to have been released very quietly in comparison.
