Finally giving this game a chance for the third time and this time I want to finish.

Are the Celestial Weapons and Sigils (and by extension, the superbosses) worth the absolute tedium they are? I've heard horror stories of what it takes to makes a single character stats and getting these weapons powered up.

I mainly want to experience the game to finally say "I played FFX".

Does X-2 have tedious stuff in it too?
