I like gold more than platinum. It's prettier, and historically was the most precious medal. Then came platinum. It's rarer and thus more valuable than gold. But to me it looks just like silver. Couldn't it have a different color?
Plus, some games like Pilotwings 64 and Blast Corps have gold medals that you can earn, and these are difficult to earn. But then they have platinum medals if you can get a perfect score, which is even more difficult! So of course I have to get the platinum, even though I would've been satisfied with my gold medal if they had just left it at that!
