The story is all right. Nothing mind blowing but not bad. It's not Matsuno level.
The gameplay is incredible though. It might even surpass its predecessor, it's really well balanced and polished. The gameplay loop will satisfy that "Tactics" itch, trust me.
The soundtrack is very strong too. I bought it on Bandcamp.
I'm actually going to buy it based on just you saying it fills the tactics itch.
Did you or anyone else get the PS4 or switch version. Is the switch version playable (as in no weird slowdown or other issues)?
