Might as well do mine...
These are in alphabetical order within their ratings since that seems more useful for others.
10: Games that were literally a life-changing experience, so significant that not just all other games but all other media must be judged in light of them.
Final Fantasy 6
9: Excellent games that either do everything right, or do one thing so superbly that they defy being lowered. Worth buying a system for.

Suikoden 2
Wild ARMs 2
Wild ARMs 3
Wild ARMs 5
Wild ARMs XF
Xenogears
8: Very good games that either aren't as spectacular in one area or have a significant flaw in another rather than just being "ok" in their weak points. If three or more appear on a system, I'm sold.

6: Games that are, on the whole, above average in more respects than below, but do not stand out much if at all from the pack. Or, old good games that haven't aged all that well. Ten or more might sell me on a system.

5: Thoroughly average games. Either they don't stand out at all or they're perfectly matched good for bad. Or they're above average games that aged poorly.
