The Secret Diary of Adrian Mole Aged 13 3/4

Sue Townsend created a phenomenon in the mid-1980s, essentially incorporating lots of sharp satire and observational humour into the diary of a confused teenager.

It might sound like an odd idea for a computer game, but Level 9 felt that there was an adventure in there.

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 The Secret Diary of Adrian Mole Aged 13 3/4 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.

Market insights

The Secret Diary of Adrian Mole Aged 13 3/4 has a steady sales history on the tracked marketplaces, meaning enough copies circulate to establish a reliable market price.

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.
