Mika,
Actually, there are not heaps of places to buy a US version online. I think there may be some sort of region codes involved. When I got GP3 , because I couldn't find GP3-2000 anywhere, I tried buying the 2000 update from Software First, in the U.K. They had it but said it would not work with my version of GP3. I can get the EA F1-2002 just about anywhere, so at least EA believes there is a market. I have followed links for "Get GP4 for US customers", but one shows it as being "out of stock", while SoftwareFirst lists all their prices in Pounds, which makes me wonder if the product is still the U.K version. I may have to e-mail them. No other online place, that I have found, lists Gp4 at all.
Last night, I e-mailed Infogrames PR department. We'll see what they say.
