first off, deepest sympathies on the loss of your granddad.
but on to the C64....my oh my what memories....what joys. many many hours spent on the lord of the rings games. loved all those types of games - yea the graphical games were great, but your memory created so many of the images when playing the LOTR games.
go north, use axe, drop bucket...!!!! the joys
number of times I told my folks it was turned off only to sneak over to it when I was meant to be sleeping and trying to type quietly on it!
