rivin2e says: The first, 6DOF, game. The second just blows it away, pushing you deeper into a mind boggling pure 3D right up there with duke nukem as one of the best.
Treat your GOGmix as your child - name it! ;)
Coming up with a cool and descriptive title should be your first priority. Being original is in your best interest - bet you wanna get lots of nice votes, right? Go all crazy if you want, but be sure to keep it civil!
So, what are the ingredients?
Pick a game that belongs in your GOGmix from the list, or find it by typing something in the text field. Relevance is key here - Earthworm Jim doesn't quite fit the "Sexiest heroines of all time" bill now, does it?
Justify your choice... Or not!
OK, so it's not required, but now that you went through the trouble of adding a game, telling everyone why you did it would be a nice finishing touch. After you're done here, add another game, rinse, repeat.
