This post got me thinking about having two games played in every match. If each game was worth 2 QP, that could force interesting design decisions and game strategy decisions. For it to work, both games would need to require a relevant investment, both in terms of match time and robot capabilities.
Or the endgame could simply be worth 2 QP instead of 2 CP or xyz points. (forget about minibots - that would be awful with QP's) What if the 2009 Lunacy endgame awarded QP? If a supercell was worth 1 QP instead of 15 points, that might have been pretty interesting. That forces you to decide if it's worth the effort of doing the empty cell setup routine or if you need to focus all of your time on winning the match.
Other thoughts: what if the highest stack was worth a separate 2 QP in 2003? What if scoring the most balls was worth a separate 2 QP in 2002? That would have changed those games a lot.
