Fuzzyfireball: Everything about DotEmu is "copy pasta". :)
It's not italian, it's french ;-)
They have really a look on gog and try to improve by adaption, but sometimes miss some points why something here is so succesful. They had also sales with 70% off where you need to buy all games. While in GOG case it's a smart way to make unwanted games more cheaper and interesting to buy, Dotemus system don't count already bought games and you need the whole whole bundle at the given fix price.
But they also try to differ from gog. They have multilingual support and try to focus and highly advertise this. Also there are some games you can't find here. All in all t's good to have two shops that offer drm-free oldies.
