This happens more frequently than it should, where in-game 'buy now' links point to an incorrect (usually non-existent) page in the store.|
I think it's because the games are written with the American store in mind and devs forget to change the URLs for other releases. When it happens just go to the store and find it manually, like X201 said.
21 consoles, 5 handhelds, 2 PCs, 1 Mac and about 700 games from the past 30 years. Every major manufacturer and developer represented. Still a fanboy for disagreeing with you.
