ok i know the idea of making an X-3 isnt that good and already confirmed its not gonna happen...but if it were to be made....i hope its like a prequel....a further depth into the characters and i would wanna see visually how they beated sin and how the final summoning looked like (i know they explained it in 10 but i wanna see how it looked like)...

so i guess if it were to happen.....it would make a full in depth insight into the characters in 10 and possibly spiras history....(without listening to that old guys mumble in x2)
