Hmm, you Euro folks suprise me. Being an OLD original Amiga person from 85-91 (Who the heck is SuperFrog and Turrican? oh wait Turrican was a value title here!).
Let's see Amiga yesteryear titles that I remember. Okay, Amiga MindWalker, Marble Madness, Shadow of the Beast, The Bards Tale and all of the Electronic Arts titles. Lemmings, Lemmings, Zoom!
The most famous Amiga software was definitely that from EA, followed closely by LucasArts (Monkey Island), Sierra Online (remember Kings Quest, Police Quest, Leisure Suit Larry). Oh and lets not forget Space Ace and Dragon's Lair by Readysoft..
Also I'd love to see Cinemaware port Rocket Ranger and Defender of the Crown (in 3d) back to the Amiga (at least doing Retargetable Versions). It's so cool even the demo version.
I have seen an SDL 3d port of marble madness called Marbles..
