1 and 2 feel pretty replayable. Great games.
3 was just okay, probably my least favorite.
4 was really fun but I don't think I'll ever want to replay it in my life. Not because it's easy as shit, but because I really don't want to deal with all the cutscenes that interrupt gameplay again. It was nice to go through caves again, and the focus on dandori and optimizing your efficiency with a set squad of pikmin was actually really fun when the game finally shuts up about tutorials and lets you play.

You know what else is interesting about people bitching about Dark Souls 3 in these threads?
There's always that one guy that bitches about heavy weapons being impossible to use because the enemies are too fast and "like Bloodborne" when a fucking STR build is the most retard friendly and easy build in the entire game. You can just fucking steamroll the entire game by knocking down enemies left and right with charged R2s, staggering bosses, and deleting health bars.
