No don't laugh!
i came across this Omnibuss Simulator from Aerosoft this week and just wondered if any one has tried it out, its a bit pricey but looking at the Demo Video's it looks very good, as most Sims represent a general feeling of scenery ,ie Flight/Train/Truck/Ship sims, this one has been made with as close to the real scenery in Berlin Germany as possible it think, you can even follow the Bus route on Google,
I have not bought the sim yet as my old PC is not up to running it, so i will have to wait a while until the boss says the ok
Cheers,
Roger.
