I just bought Empire Earth II off Ebay from a seller that had a good 
reputation, and I managed to win the auction for only $20.
The pictures on the seller's auction are the stock photographs and 
information from Sierra. I didn't notice this at the time I bid, but the 
auction also noted that the manual wasn't included and there was no online 
multiplayer (no biggie for me in terms of multiplayer and I can get any 
vital information I need from the manual from Gamefaqs walkthroughs or the 
MB.) However, I got the game yesterday and I noticed all the writing on the 
back of the CD case was in Russian. The only thing in English was Empire 
Earth II. The CD however isn't blank, it looks like a Empire Earth II CD 
should look.

Is this most likely a pirated copy? The seller is an Ebay Power Seller with 
over 1,100 ratings. I just wonder if since I may have a pirated copy of the 
game it might not play as well and it would be better to ask to return it.

Any opinions??
