I think Demon Souls is the best of the bunch, even after Bloodbourne, but I 100% agree that Dark Souls 2 ended up being the better game vs. DS1. The first game has more coherent lore, the second game more coherent gameplay. There are some silly hidden mechanics in the second game (related to dodging), but once you know about it the game really opens up. And the DLC for that game is far away the best content in the entire series, save maybe for the Ringed City in 3.For as great as the game is, they didn’t do a lot to the remaster to improve on some of those old quirks. It still is very much an older game from that era. 2&3 got better but still had some similar issues.
Blighttown is just trash honestly. Regardless of where/when you played the game.
Personally I still prefer 2 over 1 and I know I am in the minority there. I did like 3 best overall though.
