Yep, I remember it well. I spent many a night flying with only one scenery disk. But, at that time you could fly from Meigs to Champaign and that was enough. It seemed like one was always screwing with the floppy disk drive. FSII was my start in Flight Simulator and on the C-64 it was fun.
My son was just discussing his opinion of people who value graphics over game play! I had gotten him a Star Wars simulation for my computer and it took almost 1.5 hours to install! The simulation was 7 gigs of what amounted basically to .BIK videos! It didn't like my video card so we exchanged it for a chess game! I bought myself a copy of John Deere's Live Green! Much action in those fields too!
