Quoted from Kevkat:

Thought this would be interesting... We have had 12 80's games here at Blizzard Mountain Pinball during the past 6 months or so (11 are still here, Medusa's center post kicker broke and I can't find a replacement). Here are the 80's games sorted by the average number of paid plays per day:
1. Supersonic
2. Pinbot
3. Banzai Run
4. Time Machine
5. Black Knight
6. Dr. Dude
7. Mousin' Around
8. Fire!
9. Whirlwind
10. Earthshaker
11. Big Guns
12. Medusa
Yes, the oldest of the bunch (technically a 70's game!) is also the most played. Also of interest - all these games except Banzai Run are set to 50 cents per play. Banzai is 75 cents. The only game that actually makes money, after calculating rent, electricity, etc. for the floor space it takes up, is Banzai Run. However, the older games to have a following and I suspect some people come in to play them and then will play the newer things too, so I'm glad we have them!
