Sometimes funny the memories that come back reading these threads.
I had all the Epyx sports games, but mainly played Summer Games 1&2 which I had on disk. Aside from the quicker loading times and being able to join both games together, the big advantage of the disk version was that it permanently saved (and displayed) your world records.
My mum used to play games on the C64 back then and Summer Games was one of her favourites. She started a game one day when I was at school and decided to set up a two-player game and compete against herself. For some bizarre reason, when asked to type in Player 2's name she input the name of my primary school teacher.
Naturally she then went and broke one of the world records with "Mrs Eaglesham"!! I then had to spend days trying to beat it myself so that my friends wouldn't think I'd been inviting my teacher home to play me at Summer Games!
Edit: actually thinking back, it was "Mrs E" she typed as you only had 8 characters, but all my school pals knew who Mrs E was!
