The Xenoblade 2 Effect

A phenomena in which someone plays a game that is both overwhelmingly flawed and exceedingly exceptional. Enjoyment of the game will increase during the play-through as the flaws are accepted and appear less often, while the positive traits increase in quality and quantity.

"I've never, EVER, felt this way about a game. I don't even know where to begin."

"Yep. That's the Xenoblade 2 effect."
