Calling all keyboard warriors—are you addicted to drawing transit fantasy maps in MS Paint? Or, at least, sharing them on your wall with an accompanying note whining about everyone who doesn’t share your opinion? Well, put your money where your mouth is and play Metro Mini ($4). It’s a simple subway-building game that challenges you with growing a small system. You start with three unconnected stations and need to draw routes. You don’t need to micromanage anything else—trains try and make optimal time and your riders pick where they get on and get off. However, your city is growing—and you need to grow your transit system for as long as you’re able, until it grinds to a halt in a Judge Dredd-esqe social collapse. We think.
