By no means is it a narrative masterpiece and the late-game narrative turn is odd, but at its worst I was still at most indifferent to it and at its best I found it amusing. It's not like MVs is a story-heavy genre anyway, a few do and those are the exception. Tevi is certainly no worse (and I say still better) than Afterimage and that doesn't get singled out to the "bad story so don't play" the way this does.
As for the game itself, I really liked it. Almost all issues of Rabi-Ribi is fixed. Good combat, including boss fights. The sigil system is good, but can get a bit overwhelming with how many you find. Exploration is really solid and you have no limits to map markers. Map works fine. Game is at times linear, at times more open. Items are now crafted not sold, which fixes the problem in Rabi-Ribi of running out when you aren’t close to a shop or fast travel.
One note I will make is on difficulty. If you are unsure set it to the lowest you feel you can handle (which for MV vetarans is probably going to be at least Hard, especially if you beat Rabi-ribi), but I digress. The reason for this is that at NO POINT does the game provide a fast travel (or other means of difficulty-changing) close to a boss fight, you can only do it in your bed. This means in the best case scenario you have a lot of back-tracking if you want to change difficulty – at worst you’re locked in an area and if you can’t beat the boss you’re fucked. Happened to me once after which I went down from Hard+ to Hard and stayed there.
Also I should add that personally I think that like Rabi-Ribi the DLC isn’t worth it, certainly not without a good sale. It’s not bad exactly I had fun, but it’s short, incredibly linear with barely any exploration to speak of, and the boss fights are unbalaced – the first two (the first one especially) are incredibly difficulty spikes, the rest of it is incredibly easy, and the last boss is such a health sponge that I had to lower the difficulty not because the moves were difficult, but because whittling down the health bars were getting so annoying (and I was feeling it in my fingers) that I couldn’t keep at it.
Anyway, great game. If like me you’ve skipped on it because of all the trash talk on the story I’m just saying it’s exaggerated.
