I've currently got 25 inside and 14 in the garage - all operational.
The inside space gets used weekly. The garage space houses titles with lower replay value or ones I only want to play once in a while including bronze age games. Usually once or twice per month.
Most played by me - nearly every time the arcade is on:
- Pole Position
- Bitkit 2 - both horizontal (New Astro City) and vertical (MsPac/Galaga 20th Ann).
- Carnival
- Arkanoid multi with Ark, Tournament, Revenge of Doh
- DK
- Robotron
- Super Hang On
- Monaco GP mini
Least played by me - Maybe once every 10 times the arcade is on or less:
- Gravitar
- Tapper
- DK3
- Popeye
- Lunar Lander
- Wacko
- Space Invaders with multi kit
Everything else is in between or occassional use.
