Dark Tower

 Thinking about electronic games from the last century reminded me of probably the most storied of them, Dark Tower. It sold for about $40 back in 1981, which was quite a high price for that time. Over the next 30 years, complete working copies of the game got very hard to find with working ones selling for over $500. Resurrection Games reproduced the game a few years ago and even that version is selling for $220-$300.
