> The #1 tip though is that you're writing a game, or an engine, not both.
Most of the people who follow this advice will never ship anything. Stop worrying and do what you want. It's okay to reinvent the wheel if you want to learn how to make a wheel, or if you just find it fun.
While I agree with your sentiment: most people who DON’T follow the advice will propably not ship anything either as shipping is hard and rare in any case.
Or if you need a special wheel adopted to your needs. Because you were annoyed, that the common generic wheels blasted the way you drove them ... but also could not use a expensive high performance wheel, because they come in different sizes.
(But remember, if you want to ship fast, or at all, usually better stay with the common wheels and sizes)
