I have a legal copy of both Civilisation 3, and the extension (Play the World) installed on my home machine.
It works fine.
As I teach computer games at my school (yes, really!), I agree the budget to buy several copies, then lend my disc to our computer department, so they can quickly check there will be no compatability problems with our network.
While my disc is away, my mate brings his copy of Play the World round, so we can continue our saved game (on my machine).
But the game won’t load. :eek:
It just keeps repeating ‘disc not recognised - please insert correct CD’.
Is this because each disc of Play the World has some unique characteristic?
That would explain my problem - but why would the manufacturers (Firaxis games) go to all that trouble?
Does any Doper know?
