Back in the mid 80's at my frat we had this Commedor 64 and some weird game called Summer Olympic Games, my college buddies and I would compete and in the marathon you had to wiggle the joystick back and forth for like 30 minutes. We literally wore holes in our hands, they would bleed and I think to this day I can still see a mark.
The Apple 2 and Commodore 64 had some great classics that almost cost all of us our degree's, Karateka,
Lode Runner, Miner 2049er.... ah memories.
Edit:
Love the internet, I found it, guess I wasn't the only one:
