I wanted to suggeest adding a Match 3 type arcade game to the game to make units and to possibly enjoy it if its something you like. i don't like how the market was consumed by candy crush so here is an "example" video of what i mean by "Match 3" : https://youtu.be/H8TUne0DbQk?t=8s
(Of course not as its own gamemode but like the minigames in the plaza)
now i can imagine that the devs have more imporant things to develop than wacky minigames but i just wanted to suggest it. if you have an opinion on this then i'd be glad to hear it.
