I feel like this is going to be the more artistic variant of Stark. While Stark assumingely has more focus on technological innovation, I would think RM would have more focus on artistic innovation - whether through music, art, writing, or being a thought leader.
I anticipate and would love for this title to be a conglomeration of elements from Stark and Ultimate Artist, with a push to really cultivate your gifts and become massively successful, wealthy, and influential through your creative expressions.
