PC game Mini Metro is making its way to iOS, and after a hands-on demo of the game, there’s plenty of reason to be excited about this one. It is essentially a game about connecting transit lines in a number of levels loosely based off of real-world cities. New destinations keep popping up, and you must connect the limited number of train lines, with underwater tunnels and the like also in limited supply, in ideal order as new passengers and new locales start to pop up. Here’s a video of the iPad version in action:

The game is currently out on Steam Early Access, and the mobile version should be content identical to that game once it is completed. The two questions are whether the game will be free or paid, which developer Dinosaur Polo Club has yet to figure out at this time, and whether the game will come to iPhone. The size of the interface is a problem there, so if they can sort it out, an iPhone version may happen. The concept is really clever and the game looks just like city transit maps, so keep an eye out for this one later this year on iOS.
