Here’s the rub. People should be careful what they ask for.
If you want to design your own mechanics, cool.
If you want to combine them into a game, cool, cool.
If you want to share them with your community, cool, cool, cool.
It’s AWESOME to create and share - that’s a plenty good reason to do it. It’s what I do with my papercraft.
BUT, if you ask for honest feedback. Don’t complain when you get it.
Over the decades, I’ve literally seen dozens of people go “I made something out of [GAMESYSTEM] that is way BETTER than [GAMESYSTEM] - here it is!”, followed by, “What do you think?”
They are then surprised/upset by a critique (that may weaken or invalidate a bunch of their hard work). They asked for opinions, and got exactly what they asked for.
Other times I’ve seen “I’m about to do something amazing to [GAMESYSTEM] for the whole world to see - I’m gonna spend weeks/months to fix [IDEA]. What do you think?”
If you do this, don’t be surprised if some people say “We’ve seen it already, click here to download it” and “Don’t waste your time.” Those can be interpreted as important feedback - if that’s what was truly desired.
Do what you want to do because that’s what you love to do.
It’s for you first,
your table and friends second,
maybe your online community third,
but almost never for everyone else.
It’s a labor of love, baby!
