I can totally relate to this but in a different way. Music is very similar, especially nowadays when everyone has an opinion about what you should create, and it's easy to get lost in the sea of YouTube tutorials of people telling you which way is the right way, or even listening to what's accepted in the mainstream and attempting to contort your own work to fit within that structure.
After all, any form of expression can be seen as art, be it music production or games, and the constant battle we feel as artists can be overwhelming at times, especially when you want others to acknowledge and validate you.
Wouldn't it be cool if your son and his son could look back and say, "Look what my dad/grandfather created". For me, that thought is a-lot more full-filling than worrying about what the rest of the world thinks.
