Darnit! I never played Mail Order Monsters! We had the game. I remember seeing the disk all the time. One of my brother's had it. And I remember it loading from disk for multiple eternities. But I can't remember anything about the gameplay... I missed a classic? 
Mail Order Monsters was one of the greatest games ever for the C64. Pretty much everything by EA (Deathlord, Legacy of the Ancients, Wasteland, etc. etc., at that time) was, and it's a huge loss that they were never ported to the Amiga. Skipping all the technical details in the above posts, are you guys saying that Total Chaos is anything like M.O.M.? If so.... aaaargh! I might have to somehow make room on my coffee table for an AGA system! ;-)
