Tobias, again, read the post above yours. I am tired of repeating me all the time.
Machinery_Frank, forgive me but I am just curious about your claimed involvement in A7 games because you are very vague about the kind of that involvement. You are certainly able to tell which part of the game you did or are doing. Such as "I did the movement code of Betti" or the like. I know that you are doing textures and models and are selling them, and they certainly can be used in a game, but that's not working with an engine.
