The amazing artist and Amiga user Jim Sachs has posted some videos that some his work on the Amiga (and other items).
Do yourself a favor and watch 20KL Late. It is one of the most amazing Amiga games/demos I've ever seen. Even 25-ish years later, it looks great. Trust me, you will see this and wish it had been released.
I knew Jim was working on this game and that it was cancelled. I didn't remember why but with a budget of $4 million dollars, I can see why Disney bulked.
However, the game would have been amazing. I always thought Defender of the Crown had great graphics but you can clearly see how much Jim advanced from that to 20KL Late.
I believe Jim Sachs is one of the most talented people in technology. He is a great artist, composer, programmer, and director. He always made the Amiga look great!
