skeletonbow: Just to be clear though, I'm not judging anyone, but rather I'm just making an observation of how humourous I find people's reactions to people asking about Torchlight or similar, whether they are sarcastic or literally dumbfounded that someone doesn't own it already. :)
stg83: I agree as I am never surprised by people buying Torchlight or The Witcher either and find it amusing when people suggest that everyone has it while wondering out loud why GOG puts up the game on every promo. The reason is simple as you put forth in your logical analysis, because it sells really well every time. :)
Indeed, popular games sell, and giving them away on freebie promotion... well er... um... promotes them so they end up selling even more. :) I imagine there is also the potential for loss lead making people want to play Torchlight 2 and get multiplayer. I know once I played Torchlight here on GOG I really wanted to play multiplayer bad and after waiting about 12 months for Torchlight 2 to show up on GOG my buddies and I ended up throwing are arms in the air and just grabbing it on Steam. Both games are awesome and worth playing for any fan of ARPGs IMHO, but Torchlight 2 is arguably the bigger and better game with more replayability and of course multiplayer.
Sadly, Runic seems to have dried up. Either that or they are working in a bunker deep in the ground on Torchlight 3 or something and not coming out until they're done. :)
