Back in 2013, I was checking a local game store and they had a copy of Xenoblade. I'd heard the name but knew nothing of it, but since it was only $20, decided to pick it up on a whim.
Got home, put the disc in, and ended up playing for 15 hours in a row. Since then the Xenoblade series has become one of my favorites ever.

In short, the game's pretty good.
