Here there was no sensible way to buy C64 games till the early 90's. Late 80's you could find few games "under the counter" in shops specialised in electronics, if you asked. They were usually expensive garbage and picked by someone, because of the cover art. There was always the one obscure flight sim for adults that was also shit.

So 100% illegal copies.

If somebody found a good game it was quickly bartered and copied to everyone else.
