Well i just saw the added bit at the end of your original post so..

Ive played CT twice if you count new game +, ive seen most of the endings on my second play through. There are only about 2-3 i havent seen.

I'd give the game a very high rank. Its got great story, gameplay, characters and music. Even the graphics are nifty. And it has alot of unique features like the whole travelling through time thing and what you do in the past effects the future, and the double tech system thing is cool too.
