If you're a fan of Puyo Puyo or Tetris, this game is worth a buy. This game is essentially a crossover between Tetris and Puyo Puyo, not only including modes that are straight up Tetris or Puyo Puyo, but even including crossover modes between Tetris and Puyo Puyo. The game is loaded with gamerscore, supports 2 controllers, and runs at a smooth 60fps. It's region free, so it will play on your American Xbox One console.
It also features a story mode, which is really just a series of set missions (Clear so many lines, battle the AI, etc.)
For the price this game is selling for, it's definitely worth a buy.
