I am 50. My first computer was also a ZX81 with 16k 'wobble' pack (although that came at a later date).
Elite on the BBC was the most immersed I've ever been in a game - that 'reality' was a product of my own imagination.
Once VR has ironed out its wrinkles and matured a bit, it will surpass what I ever envisioned would be a reality in my lifetime.
I'm working on my dream ...
Edit: Oh yes, and there's Voice Attack to go with that.
