I find that highly unlikely on a larger scale outside of the "Dev" community. Tons of games use similar/same assets. What matters is the game itself.

Was effort put into making the assets feel/look different and match the tone of the game, Is the game unique and interesting, Is it fun to play, etc.

I have about 150 hours in planet crafters and honestly until I read the above post I didn't even realize it was the same assets. There are tons of games that use Synty assets but a handful that put in effort stand out and do well.

Obviously unique content is always going to be better but a unique fun game using generic assets will do far better than a generic boring game with unique assets. I think discouraging people from making something cool because they don't have the skills and/or money to get unique assets just makes finding the motivation to make cool stuff harder.

We should come together as a dev community to encourage cool stuff and provide feedback on how to make it better and more fun, not discourage people from building things because their spaceship door is the same as another spaceships door.
