I personally haven’t played the Souls games. Tried DS3 and after 10 minutes, and I knew it wasn’t for me. I honestly will never understand the fascination with the genre, but mad props to those that love them and put in the time and dedication to master them. As far as ranking the FromSoft games I have played, it would be:
1) Armored Core 2
2) Armored Core 6
3) Otogi: Myth of Demons
4) Lost Kingdoms
5) Otogi 2: Immortal Warriors
6) Armored Core 3
