It's kinda scarey reading about all the problems folks seem to be having.
I've had the game since it's release, and so far the only drama I've had is with Mission 4 of Operation Wesserbung. And the work around on the German gaming site fixed that - and that was only on the German side, the British side ran fine. Otherwise the game has performed flawlessly for me.
I haven't a particulary powerful system, but with some graphics turned down the game does run well. Guess I'll keep my fingers crossed.
