Last question: How will this work if me and my friends want to sell our game? You might be asking why professionals are using a tool like craftstudio to push out a game.
My friends aren't programmers. I'd rather them trying to figure out craftstudio than teach them opengl/webgl/direct3d.
Everything you build with CraftStudio is yours, entirely (as long as you're using only assets that you own the rights too, obviously) - See http://craftstud.io/terms for details. I wouldn't want to ruin a good platform by providing unfair terms.
