I really like the game. However, once you reach level 20 there isn't much left to do. Missions take 3 hours, I can't build anything and there isn't much to do with other players - besides help them build or steal stuff I don't need anymore. I'd like to see some new building (maybe have a class requirement like a clinic for the medic) . Mainly need some sort of coop with other players against herc troops or something and some sort of faction system.
It would be nice if players could get a bonus for inflicting 0.1% damage to a world boss instead of 1% - or just give the bonus to the top 100 players as that might scale better as people level up. So far I've only seen the top three people even get to 1% and they get other bonuses.
There was a problem. The specified queue is full.... then how did I click to build something? It's annoying that you sometimes need to wait 5-10 seconds after something is built/upgraded to build/upgrade again - it's really annoying when just starting.
It's cool that the game lets you see all the endings in one play through. Just make sure several don't happen on the same day or you only see the first one.
