My kids (4 and 8) love stardew valley. Also it works on every device.
Been considering don't starve for a while.

As others said, in-depth design is often skipped, especially if the dev team started very small.
Sounds like your intuition is right, though - the lack of design bit them on the ass when they realized they missed a part.
I have also been laughed at when I suggested a UML diagram in the past. However, it is helpful. For more visually oriented people even more so.
I'd suggest to go ahead and do it, unless your boss is adamant that it is a waste of time. When they see the result they might be happy.
Funnily, due to this, i often find an open source app that is way better than whatever annoyed me.
Just today i used an Adobe product that got me raging. Within minutes i installed an oss equivalent that was a joy to use in comparison.
It's an interesting trend.
