One of the projects I'm proud to be part of is a classic Amiga game called Deluxe Galaga.
We are in the process of completing this game for the (Linux, Mac, PC) platforms.
My focus was to make sure we retain the original look but double the resolution. While these samples may not be final versions you can see cleaner edges (Antialiasing) and smoother gradients. More refinements has been spent on the asteroids though.
