Some very interesting and could be easily ported (too late for that ehm?)...
Some proposals were outrageously stupid.
So to contribute to the second category: Someone please port Crysis.
Now to the real point... With the exception of some, most games wouldn't give you the original feeling even if "relatively succesfully" ported.
For example I would say to port Pitfall 2 (possibly some PD build is available) or Hutchback or Oil's Well or Dinosaur Eggs from CBM64 to Amiga... I doubt they would trigger the same feeling.
