I even started with VB3 ^^
But yeah, VB6 was so much fun in its time, and was a good base, developper-wise, to handle other languages after (C had, to me, a lot of similarities with VB when I started to learn it).
Tbh, the last time I launched VB6 (a few years ago now), I was quite lost in it though. It took me quite some time to realise a simple app that I know I could have done a lot faster during the time I was used to VB ^^
