Good call on that. My immediate examples that come to mind are the things I mentioned off-hand in the other thread. Xenogears, Final Fantasy VII, and Knights of the Old Republic (both) all had confusing or disappointing endings. Final Fantasy VII was so ambiguous there were arguments for years after on whether or not humanity even survived the ending at all

Xenogears ruined any chance of a sequel or continuation in any way by (SPOILER) making all gears non-functional for the forseeable future

And both KotOR games (even though the first one had an epic boss fight) ended on pretty much the same note. And I'd almost call that ambiguous if not for the fact that they kind of spelled out the stupidity: (SPOILER)your character, in both games, goes on a quest "to the edge of the galaxy and beyond" to defend against unknown enemies that were stirring outside the known universe and threatening life within the galaxy. It seemed like such a cop-out and gave absolutely no closure. Especially in the second one where they admitted a lot of things were cut from the ending, and your list of options dwindles dramatically. So there's a good chance some or all of your favorite characters aren't even involved in that ending. Lame
