Been playing since it started as an app. I'm at the stage where every researcher is maxed out. It takes so long for new ranks to come out, sometimes longer than 6 months. I don't think you've taken high levelled players into account as after all the waiting for updates nets me about 1 week worth of gameplay. Doing extra events is pointless as I have millions of science that can't be spent since everything is maxed out. Can you introduce some kind of prestige system?
