I think the answer to this question is going to revolve around when one started playing RPGs.
My first taste of roleplaying was via AD&D - all my friend had was the DMG and we had to call another friend to see if I had leveled. Cyrus the Fighter made 2nd level in that first solo adventure - I'm fairly sure we didn't accurately count the expo, but that didn't matter. The experience was magical and I was hooked for life.
