I grew up on a smallholding farm. My Dad is very hands-on and practical, he’s worked as a landscape gardener, fencer, teacher and more. Although some things he does are quite ‘bodge-y’ he fixes and installs things himself, including plumbing and electrics. He isn’t very good with computers so I ended up filling that gap.
My past experience in games design is also very informed by DIY, with the indie game scene being one of the most ‘DIY’ modern cultures in my opinion, as you have to learn how to make every part of a game (the mechanics, design, visuals, audio, etc) all on a limited budget. Thus there is a reliance on open source and free to use software, with a close connection to the culture of forums and sharing code.
