Final Fantasy X
FFX is the tenth installment of a series of roleplaying games produced by Square Enix. The story revolves around the nauseatingly dense but ultimately well-meaning Tidus, who is thrown into a strange world called Spira, where a mysterious entity called Sin sows mass destruction on a regular basis. The summoners and their guardians routinely make pilgrimmages to a sacred place called Zanarkand to rid the world of Sin--but Sin always comes back. This year's contending summoner is Yuna, a vapid but surprisingly determined young lady who wants to follow in her father's footsteps and save the world. Auron is introduced as an acquaintance of Tidus' and a guardian of both Yuna and her father.
Final Fantasy X-2
FFX-2 picks up where FFX left off, with Yuna and her cousin Rikku joined by the stoic, somewhat cliche-ridden Paine in their search for treasure spheres. Yuna's ultimate goal, though, is to trace the origins of a particular sphere which appears to contain a message from Tidus. Auron has a few cameos throughout the journey, most notably in a snark-tastic sphere recording during which he interacts with the delightfully abrasive supporting character Gippal.
Kingdom Hearts II
The amazingly popular sequel to Square Enix's and Disney's Kingdom Hearts and Kingdom Hearts: Chain of Memories, KH2 continues the adventures of Sora, Donald, and Goofy as they look for Sora's missing friends and kick some bad guy booty. Auron appears in Hades' Underworld as a stoic fighter brought back to life by Hades to match brawn with Hercules. Auron, however, has other ideas about how he'd like to be spending his time.
