Picture a field in your mind and scale the size of it according to these phrases. Number of PC gamers in the world... BIG... number of PC gamers who love simulation titles... quite big... number of PC gamers who love trains... getting smaller... number of PC gamers who love simulation titles about trains. Okay, you get the general idea - it's a small market but one that's certainly worth a publisher having a go at. Microsoft thought so too, and seven years ago they commissioned UK-based Kuju Entertainment to produce their first Train Simulator game. They had planned a sequel but things went wrong for Kuju for a while, forcing the cancellation of the deal. However, the plucky developers soon got back on track (groan) and ploughed full steam ahead (even worse) with their own Rail Simulator - "an authentic railway experience."
