Ok so, first question: how does getting rid of more minigames affect popularity? People can still play the old stuff they like.
Second, where in the world have you seen Battlezone and Bingo getting updates? There were a few, to BZ only, right a few weeks after its launch (and it's dead now, while Bingo strives to survive).
And third, Eggwars got already plenty of updates in the past few months, I don't see a point in your whining about it being ignored and devs working on stuff bound to become deserted in a few weeks.
