so, correct me if im wrong, but there are 3 endings, no?

Okay 1st-limited completionjust kill the final boss, no tidus

2nd- do a certain strain of events, invloving pushing X at the farplane and whatnot, i think? See tidus?

3rd- 100% do ever single solitary thing, and happy ending with tidus and yuna reunited

please help to clarify!
