Train simulation games rarely get the praise that they so often deserve, so we wanted to be sure to recognize NimbleBit's newest game, Pocket Trains, for the deliciously complex empire-building that the game lets you jump right into. Build up your railroad company all across the world by collecting coins, unlocking new trains, tinkering with routes and train speeds and, of course, transporting your busy passengers from city to city. If you enjoyed NimbleBit's previous transport title, Pocket Planes, then you'll have no trouble taking your talents to the tracks here.
