I would second the original sentiment of different categories and more tailored systems of rating for older games. The current rating categories are obviously modern-skewed. I say this as a dude in his thirties, so let's not make this a "blow-off-the-old-guard" situation.
At the very least I would think it would be possible to personally sort the results you're looking for (by the categories listed above by Pecos.
Good idea, Pecos.
