Mini Metro MAR 13 2014
Mini Metro is an upcoming game in the style of Sim City, except you're only building subway lines.
Mini Metro is an upcoming minimalistic subway layout game. Your small city starts with only three unconnected stations. Your task is to draw routes between the stations to connect them with subway lines. Everything but the line layout is handled automatically; trains run along the lines as quickly as they can, and the commuters decide which trains to board and where to make transfers.
However the city is constantly growing, along with the transport needs of its population. How long can you keep the subway system running before it grinds to a halt?
Oh man, this is great fun for transportation nerds. Site says it'll be out in "early 2014" for PC, Mac, Linux, iPad, and Android. You can play an early version on the site or d/l an alpha version for OS X, Windows, or Linux.
