Family support for becoming a dev?
HA! None at all.
Well, to be fair, my parents bought their first a PC in 1996 for learning how to use it and to write documents for business.
So it was a rather passive support, if at all.

Dad bought me a Gateway back in the late 90s when AOL came out. As far as support that's where it stopped. Especially when I ran up a big internet bill. Than the internet stopped lol. I feel your pain.

Back than I wanted to work for Nintendo. That's a laugh now that I know their ridiculous hiring requirements.
