I loved the original and Second, but I played the demo for II and it did not click with me at all. I really disliked the change to how turn order worked, the original system dovetailed so much better with the titular Brave/Default mechanic.

I immediately regreted it after buying it

The game is pretty mediocre

For the most part, the story is nothing to write home about and it's not exactly the most beautiful game out there. However, I think the mechanics are great - I did enjoy my time with BD2 a lot and would recommend it.

That being said, if you don't enjoy the gameplay, it won't change that much. You just get more classes.

I enjoyed the 2nd, but most of the things were very cookie-cutter generic. I liked that style to an extent, but it just becomes very predictable and after a while and I wanted to just finish it by the end. Decent enough story I guess and could have been worse. Fighting was probably its best part.
