I'm torn between the two methods - I like the "full closure" type endings, as it makes you satisfied that you've made their world a better place. After all, that's what it's about isn't it On the other hand, some of the most abrupt and annoying (at the time) endings, most famously FFVII, have triggered years of debate, discussion, fan fiction, imagination and theory-making. And it's always been a LOT of fun. So I'm not too sore about the very abrupt ending.
