When I was 12 I made a stop motion animated dizzy egg style adventure game in HyperCard. When I was 25 I remembered and thought, hmm maybe I should try and learn how to code. I'm now a professional developer.
As an aside, I sold it to my school mates for 50p a copy. When they asked why they couldn't just copy it themselves I told them I'd installed DRM on the floppy disks.
What's cool is that as I made these games I kept wanting to add more to them (interactivity, sounds, etc) so I ended up doing some scripting as well.
As a 12-year-old, this was amazing - my first introduction to "programming" but I didn't know that at the time.
