For those of you who fondly remember 1994's Transport Tycoon, you might be interested to hear that it has been designed for touch screens and is releasing on iOS on the third of October. From the mind of Chris Sawyer who started with this humble franchise before moving onto the Rollercoaster Tycoon games, this port has been made with much deliberation on how to transfer the rich simulation gameplay of the PC version onto the iOS. There's also a trailer!
A word of caution: the tycoon games usually whittle the hours away. Approach at your own risk!
