Keith_I2: What kind of deal is made with game creators?
everyone on the forums is a cynical bitter lonely old man emotionally invested and subsequently let down by GOG ;)
To try to answer your question, here are my guesses: for new games, the devs and publishers are small enough that the small money they'd get from GOG would be meaningful to them; GOG basically only gets scraps from AAA devs and publishers (and I don't think we've gotten anything recently from them), and lowered their profit share to try to attract more; GOG agrees to do technical work in exchange for releases here (Blizzard games, Konami games, and basically all "good old games" in the past; not sure if they do anything on Piko releases).
