Out of curiosity I have bought P II Gold. It installed fine but the video intro had to be excluded in the command line.
Some changes I noticed are that official notices appear in the top left rather the top right of the map. I missed some charges

Most annoying are the BTDs. It may be that this will not be an issue with Win2K but XP Pro SR2 has an issue with the German version of the game. About every 15 - 20 minutes I get a BTD where, in most instances, the game just closes. Soemtimes I get Gate's notification that the program encountered an error, he apologizes ec.
I will e very relucant to get the "free upgrade" for Vista. Even if I should let them send it to me, it will remain in the wraper until SR2 is out.
I have Win2K on one computer - it's the most stable platform I have ever seen out of Redwood, but it has P III and I don't want to mix programs of the same manfacturwr since I am afraid it might bugger up the registry.
