Atari has just released RollerCoaster Tycoon Classic, a "new" game for mobile based on the Atari-produced theme park sims. Classic takes its cues from the original RCT and RCT 2, offering a more simple take on park design, construction and management than more recent titles in the series. It's also the first RTC game for mobile that isn't stuffed full of microtransactions. Instead, you pay $6 (£4.50) once and then you own the game. Innovation!
