10 Secret Video Game Endings That Took INCREDIBLE Effort To Unlock

2. The 100% Ending - Final Fantasy X-2

Final Fantasy X-2 has several different endings, and unlocking the "perfect" ending requires players to achieve a 100% completion rating. Much like Valkyrie Profile, this is nigh-on impossible to achieve without using a guide, and a simple mistake will ruin your entire run.

Every chapter in the game has a laundry list of quasi-random activities and interactions for the player to check off, and unless you're paying close attention to the list of requirements, you can accidentally steer yourself wrong with ease.

Players who slog their way through to the end will get to see an extended reunion between Yuna and Tidus, but unless you're really in love with the game and its characters, your time is almost definitely better spent doing literally anything else.
