Most of my favorite RPGs either I haven't actually beaten, or had very terrible (or at least lack luster) endings

As far as endings I remember, to games I actually beat, and ones I actually enjoyed... I can only think of two...

The first Mass Effect and Final Fantasy VI

Mass Effect had a fairly happy and/or cliff-hanger'y ending that could have likely stood on its own and let the players use their imaginations pretty well

And while Final Fantasy VI's ending was pretty bittersweet, it tied things up extremely well, and gave a lot of closure

Mass Effect 3, KotOR 1 and 2, Xenogears, Final Fantasy VII all had weirdly ambiguous or completely disappointing endings. And my other favorite RPGs I haven't beaten. So I have no idea how Baldur's Gate or Xenoblade Chronicles ends lol and a lot of other RPGs I adore. Very sad thing
