About this game
As the Mad Doctor, you decide you'd like to build yourself a monster.
To do this you must find body parts for your monster.

To get these you can dig up graves or stealthily attack lone walkers late at night and beat the stuffing out of them.
Then you take them back to your castle and either finish them off or lock them in your little dungeon until you're ready to 'request' their assistance in your endeavor.
Finally, when you've found choice parts for your monster, you must take him to stonehenge (cliché alert) and have him struck by lightning to come to life.
The residents of the village are not especially impressed by your idea and will attempt to stop you.
Unlock the dark side of your psyche, turn the lights down low, put on a maniac-type laugh and go build yourself a monster.
About Commodore 64
Released in 1982, the Commodore 64 is the best-selling home computer model of all time, with an enormous software library spanning games, productivity tools, and everything in between. C64 game collecting centers on cassette tapes and floppy disks in their original packaging — physical media that's inherently fragile, so complete, working copies from the era are increasingly prized by retro computing collectors.
Gamevaro tracks Mad Doctor for Commodore 64 with separate market values for loose, complete-in-box (CIB) and factory-sealed copies, sourced from real eBay sales. Prices also vary by region — PAL, NTSC-U and NTSC-J releases of the same game often sell for different amounts due to print run sizes and regional collector demand.
Adding Mad Doctor to a Gamevaro collection takes seconds — search by title or scan the box barcode, and the app fills in cover art, release details and current pricing automatically. This C64 release dates back to 1985.

Rarity & condition
Only a handful of market sales have been tracked for Mad Doctor, suggesting it doesn't trade hands very often — a sign of relative scarcity compared to more common Commodore 64 titles.
Complete-in-box (CIB) copies typically command a premium over loose cartridges/discs because the original box and manual are more fragile and get discarded or damaged over time — fewer complete sets survive.
