I don't agree with what you're saying about merit = percentage reward. This rewards highly-polished pieces of shit, because you're rewarding companies for their ability to throw nice graphics and flashy effects to cover up gaping holes of story and/or gameplay. This is the problem with Final Fantasy games, which have stagnated for generations. FF14 suffered a lot, and it's being remade to fix all the issues it started out with. If everyone simply rewarded it based on the effort those guys put into making vast cities and complex bosses with great animations, the game would still be crappy and continued to be supported instead of going through a reboot and having the company learn from their mistakes.
Games have to be valued by the full package, not broken down into small chunks.
