TheJoe: It seems that the recommended games are always Fallout and Freespace, they're also always the games "Other People Bought".
Who's paying GOG to advertise? Where do I sign up? I need a bit more cash.
The recommended games are based on which ones are the best reviewed and best selling (IIRC). Obviously, since the Fallout and Freespace games have been available the longest, they have been the biggest sellers and received the most reviews. The "Other People Bought" is just what it sounds like, other people who bought the game you are looking at also bought Fallout and Freespace (I don't think many people have
not bought those games). It should also be noted that if you buy a game, it will no longer appear in the recommended or "Other People..." lists for you, something else you don't own will take its place.
