I'm not sure what this has to do with anything. We're not ranking based on potential. We're ranking based on performance. Could Melee win the whole thing again? Sure it could. I doubt it because I don't think the voters will allow it to repeat, but it could. Is Melee looking better than RE4 right now? Not really.
I'm not ranking on performance. I'm ranking based on which game I would expect to win a match, right now. That is strength, and you quite naturally should consider any information that impacts that evaluation.
