Construction Simulator 2014
 

Just a heads up for anyone who has time to kill on their IOS device.
Construction Sim 2014 is worth checking out. It's got real world euro models and enough tasks to keep me busy for a while for when I'm couch-bound. Tippers, forklifts, flatbed, mini and full size excavators, cranes.. The excavator is suprisingly realistic. Lite or full version can be found in the App Store.
