I roleplayed that I was a cat for a few years.
If I knew then what I know about furries now, I'd have immediately moved on to my scientist/archeologist and/or detective/spy phase...D:
And of course, there was playing House and the like, but I preferred to throw in fantasy twists like having a pet dragon or playing as a family of giants. I also played console games, but started out with Crash Bandicoot and Gex. I didn't discover Final Fantasy and Zelda 'til after I found online play-by-post.
