Is it any good as a moo-sow game? I mean, compared to the quality of say, any of the DW Gundams, Hyrule Warriors or even the Kamen Rider Battride War titles, which I quite enjoyed.
I enjoyed the game overall and it got me into Fate, but there's a couple of things about it that might sour you. Some already mentioned:
-The main story mode's cut scenes are so long and drawn out that it might as well be a visual novel with musou battles inbetween. There are four stories to play through and some stuff will repeat itself each time (purposefully- it is tied to the story).
-Don't like waifu~? Don't play this. Each main story has you playing as a female (Saber Nero, Caster Tamamo, Saber Altera, and Saber Nero again) and the cut scenes are full of them gushing all over the protagonist.
-All of the other characters are restricted to free battle and smaller story modes, with less stages to play and little story (which, depending on how you look at it, might be a good thing, lol)
-There are few enemy types in this game, and combined with re-used stages, the action can feel repetitive, even for a musou.
-There's a heavy emphasis on conquering and maintaining control of the zones on most levels. That's certainly found in other musou games, but what can get annoying is that there's a specific enemy type that will cause enemies to start populating in zones. These guys will pop up and cross over into other zones (you get a warning on the map) and start to cause them to get taken over. You can get caught in situations where these little fuckers start to pop up in more than one location, and no matter how quickly you dash over to one zone and take one out, the other will cause the other zone to get taken over, and by the time you get to that zone...another zone has been taken over. This happened to me a few times, and while I was able to beat the stages in the end, it made some battles drag on for quite a bit.
That said, I had fun with this title and even though I double-dipped on the PS4 and Vita versions, I'm getting this on Switch as well (mainly for the Japanese LE version...I want that case!) and will do some replaying, albeit skipping all the cut scenes, lol.
