Great game, extremely high replay value, beautiful graphic! I'm highly hooked, been playing the game for few months since release.
Lots of skills / gears combination to choose from. Unique mastermind style (summoning creatures / traps / rifles by using different cards).
There are some balance issues, experiences player in group can be OP. (or Mastermind can be OP v.s random casual players).
Some lagging issues because it's p2p system, overall if it's within similar regions I personally don't experience lag.
Game is still quite young and new, and it's possible it will be sold separately without needed to purchase Re3.
(This review is simply for PS4 version, PC version is full of hackers/cheat code and is not recommended!)
