Bravooo! Excellent post. Everything you mention is important but the main thing is to have ONE IDEA. A creative that satisfies you, that excites you, because it will work with passion.
Also remember that there may be errors in the finish but what else has no errors? Even in large corporations with thousands of employees occur games with imperfections.
A great pleasure to have read you @vladalexan
Yeah, bugs are indeed a mainstay of everything software, especially video games. For proof, just look at everything Bethesda released so far. The essential part is squashing the game breaking ones.
