The first one i played was ds2: Scholar of the first sin on xbox one. That sort of got me hooked on the series. After that I picked up a ps4 in mid 2015 just to play bloodborne, i got the platinum in it, when dark souls 3 came out I played that too on xbox one and got every achievement. I tried ds1 but i didnt like it as much as the other games, i actually preffered ds2. I never played demons souls when it originally came out, i just wasnt interested in that type of tough game in 2009. Most of the games i was into back then were more of the mainstream titles, your uncharted’s, gears, mass effect, ect… i finally did play demons souls on ps5 and i enjoyed the fuck out of it, got the platinum as well. Sekiro did nothing for me because i just dont think feudal japan is an interesting setting (sorry ghosts of tsushima) and i played about 50 hours of elden ring, but did not beat it, i actually burnt out on it. I dont like it as much as the other souls games i played.
