Haha..
Got it. It's not anything I've ever looked into or heard about so I was just curious.
I have however seen developers release demos after a games release.
After that demos started to cease being made, atleast on last gen.
I guess I was relating it to the console side there.
It looks like The trial versions of digital games are the new demos and seem to exist just to make you buy the game.
You can't really give feedback on the trial version. Kinda crazy what it's become.
