This game, "3671 for exA", has been reborn with a tougher gameplay and a more e-Sports-oriented presentation. I've been watching the manager play, and as his skills improve, you can see another dimension. It's not monotonous and repetitive, but a player's high awaits you. It brought back memories of my elementary school days when I honestly wanted to get better at the game.
It's so much fun that I don't mind the retro look at all. Rather, it's a fun game that asks the question, "What is a high-spec visual game?”, and “what is a pay to win social game?” It's a great toy that allows you to compete with other players in terms of skill. If you find it, please give it a try.
