Dark Souls 3 is really amazing. It easily takes the second spot in the Souls ranking for me. I know Blake didn't love it as much as I did, but I played it like 3 or 4 times back to back after I got it. Once the DLC drops, I'll be going back again for a fresh playthrough.
I mean, realistically, I love all the Souls games almost equally. They all have different quirks and rhythms, despite all being very similar. These small differences make them interesting and fresh to come back to after playing any other game in the series. Basically since Dark Souls came out, I've been playing through a Souls game, which is kind of insane, but I just can't get enough. Despite knowing and seeing basically everything, there's almost always something new to see and experience or a new play style I haven't tried to make it seem fresh and new. Those games are all master class.
