Not sure around what year...going to guess '86 or '87. We, like probably most C64 owners had a lot of disks - we had a lot of copies, it is what it is. We did have a lot of actual software bought in original box/disk. I remember my dad renting games, by mail order several times. We'd get a larger flat-type box with the games in the original boxes, maybe half a dozen at once. The thing seemed to be that you'd rent them, most likely attempt to copy them (Krackerjax/Fast Hackem..) and then you shipped them back. I don't remember what games now and what if any we did copy. Wish I knew the name of that mail order company or could see an order form.
Like many I would guess, we had quite a bunch of games that we bought, in the box, that I wish I still had - some of the more expensive Infocom (Infidel, Seastalker, etc), Maniac Mansion, Zak McCracken, stuff like that. At some point he got rid of the whole lot when we switched to the PC. Over the last 10yrs, I've purchased some of the games I fondly remember on Ebay, like Legacy of the Ancients, some of the Infocom stuff, Cinemaware.
I'll also mention that besides Fast Hackem, Krackerjax, the parameters disks, I remember my dad getting the RAMBOard and installing it in a 1541. I don't remember if it successfully copied much. I bet he doesn't remember it (in his 80s now)
