My ranking of Classic Role Playing Games (CRPGs) based on how much I enjoyed them.

What classifies as a CRPG, or a Classic Role-Playing Game, is a game with the following features: isometric camera, party based gameplay, high variety in character and class customization (with stats, skills and all elements related to RPGs), deep story where your actions can affect the outcome, role-play opportunities (as multiple dialogue choices that reflect characters with different personalities and alignments, like being able of being evil or selfish) and luck based combat and gameplay (as in dice roll based).

As for which of these features I like the most and are most important to my enjoyment: I highly value games with rich story, setting and premise, where you have ample opportunities to affect the outcome of quests by making choices and can role-play by having various flavor based or directly affecting the story decisions and dialogue choices. I don't really enjoy luck based combat (I am unlucky as hell) and I don't bother min maxing stuff, so games more focused on combat will not rank highly in this list.
