I've been playing this since the JP launch, and can say that the Global version got screwed in the early days. To many events all on top of each other, impossable to grind out all of the for a FTP.

If you don't like gacha games, your not going to like this. Very grindy, with very tough rates. That being said, the art and music is really good. I certainly enjoy the game enough, I just know that for most people, it's not going to click. Without a clear connection to the main franchise, ReIn is worth skipping for now.
