Foxhack: He's referring to the people who buy the megapacks that include games they'll never touch, NOT people who buy games for a reason. How many of us have had to buy a pack on Steam because buying that one game you want on its own is more expensive?
Actually, he was making a cheap shot at Steam deals. GOG can't do them because it is lacking the massive user base of Steam. A 75% sale only works if you have hundreds of different games millions of diverse customers. GOG can't do that (yet), their "GOG gems" are the smartest and best they can do in that way.
GOGs user base is massively different than that of Steam. Steams is a massive blob of people with all kind of preferences, while GOG has a much smaller, but much more dedicated fanbase. I bought just about all Eidos games on release for full price, because of support for GOG "fighting the good fight". Not because I had any need to play those games. I've been most of them twice anyway. And I'm not in a minority here.
Instead of acknowledging that and focus on their services (which includes are very awesome community, btw) for the "higher prices" they charge, they took a cheap shot at "stoopid gamers".
Usually TET is doing a decent job at marketing, but where was his mind when he approved those answers...
Edit: Oh, and how does this statement add into the "buy one more game for a bigger percentage drop" they had running? Jeez, that sentence, especially highlighted like this, will cost GOG sales. And I'm not talking about mine....
