Total Chaos is historically significant because if I couldn't play that game I would have sold my Amiga and moved on years ago. It keeps the Amiga alive for me.
An A1200T serves no practical purpose. If all you want to do is play old 80's action games then all you need is an A500 for that.
My friends from work would laugh at me if I invited them over to play Civilization on my Amiga. But when I invite them over for a Total Chaos Party they are in. Let the monster mash begin!
