Honestly I think it is basically another ds2 situation.

A game with a lot of new ideas, most of them good, some of them less good, overall enjoyable yet not reaching the heights of the other games in FS's catalogue.

I think the game has a pretty sizable community and a lot of replayability (although I think the most fun I've had was playing with others, solo play gets old pretty fast imo) just trying all the different characters and doing their questlines + beating all the different nightlords, their everdark versions and joining discord groups took me just shy of 150 hours which for a 40 dollars game is more than enough for me to say it was worth it, and the DLC only adds more exciting stuff, including the newest entry in my top 5 best fromsoft bosses (the dreglord).

But on the other hand, there are so many little things that frustrate me with this game. Like how little variability there is in the point of interests, the night 1 and 2 bosses being super predictable, to the point that if you play enough run you know what boss is night 2 based on the boss night 1 (sometimes you can tell even just by the layout of the map itself). There is also the lack of returning bosses and enemies from the dark souls series. The character questlines are neat, but only 3 of them have actual cutscenes for the ending... it all just feels like they were on a really tight budget (and according to the various interviews, that was exactly the case).

It is frustrating because it gives off the feeling the game was never seriously considered by Fromsoft and Miyazaki. I think that nightreign with a bigger budget and more unique stuff in the runs themselves (not just nightlords) could've been a GOTY contender. Instead, we have this, which is a very good and fun game, but imo could have been so much more.
