There's many more that I'd love to see in GOG, I hope some of them will be here eventually. Meanwhile, I still have enough items in my wishlist to go through in the next few years. :)
damien: I'm a big AMIGA fan, I am assuming you are too. You should check Amiga Forever out, you will be able to play some of the listed games in the best possible format.
I never had an Amiga computer, nor did my friends, sadly, so I didn't have the chance to experience playing games on it. I went from the Commodore 64 to a PC. I remember, however, how the old magazines always had screens for the C64 and Amiga versions of games next to each other, and the Amiga were always the best looking ones. :)
