I purchased Micro battles 1 and 2 after playing them with my friends, and they are really fun head-to-head games. Being either turn-based or timing-based, they were simple and gave both players a good experience. However, I tried the new app, and it just doesnt seem very good. I only tried 2 games, with the first being a robot shooter where you run around randomly waiting for a lazer-shooter to spawn just for your opponent to easily dodge them. The game takes forever and is just boring, let alone make sense. The second one I tried was a race-car game, where everything was literally done for you and minimal player output was needed; you just steer to the left 1 or 2 times and you win. Another problem with this game is that the player who started in the inner ring has a pretty large advantage, whereas the minigames are supposed to be balanced.
TL:DR - Skip this and get MB 1 or 2.
