Yes, Gamersgate approached us and asked whether we'd like to sell Driftmoon on their site. All the distributing services take a much larger cut than what we get from selling directly, so if you want to support any game developers, always buy from them directly. Having said that, we're very glad to be working with them, since many gamers prefer to buy their games from one platform.
Thanks for notifying us Maltose! The dollar pricing seems to be a mistake, we'll get that fixed to the equivalent of the euro price. Consider it a short unadvertised sale, better grab it quickly while it lasts.
