All about:

Broken Studios was originally a small studio on Scratch.  It was created during the time of "Scratch Wars: Season 1". It was created by Creapbro_64, Winkydinkydee, and Rock-Joen. There were just random projects, in that studio.

Broken Studios later upgraded to "Broken Studios +!" It wasn't anything different, from the original Broken Studios. It just had the same sorts of projects.

Later, Creapbro_64 and Bazzario were developing a new game, called: "Creapbro Crew Quest". A bit later in development, Creapbro thought of the idea of changing their studio name, from "Creapbro Crew Entertainment", to "Broken Studios". This is the Broken Studios we all know today.

But, a little bit after the current Broken Studios, Creapbro_64 started upgrading Wahooo-353's games, giving them a pluses, after their names. Creapbro wanted to give these games different branding, from the original Broken Studios. He decided to put a plus after Broken Studios' name. That's when the current "Broken Studios +" was born.
