Dude I worked with Unity for around 8 years.
When I was a Unity dev I had tools on Asset Store as well.
Because this is what I do, I make games and tools I create I sell them too.
The path you are at right now, I ensure you I’ve been there; if tomorrow I’m forced to leave UE4 and go work on Game Maker then I will go there and make tools for Game Maker as well… You’re trying to find something to attack because you’re mad about something someone said online, I understand
