The game itself is pretty fun, but as you recruit more and more people the lag makes this game unplayable, even before you reach a win scenario, and even with no other apps running in the background.
I spent over half an hour just assigning people to scouting missions, saved the game to be sure, then received a phone call a few minutes later, after having ended the day, yet after my call I was still brought back to a save even earlier than my scouting assignments. After frustration like that I just want to give up and not play any more.
I struggled between rating this 2 or 3 stars just because of lag. If that issue could be resolved, this game would easily get 5 stars out of me.
