The Ultima game that Garriott was talking about was Ultima IV: Quest of the Avatar, which is widely considered a high point in the series, including by Garriott himself. It was a huge departure from the way RPGs were/are traditionally designed, which was a response to a combination of the 1980s moral panic going on in the US in the wake of Reagan's election, and Garriott's own concern that the earlier games encouraged too much thievery and senseless killing from supposed heroes. There was no overriding villain to defeat. Your quest was to become the Avatar, the personification of the Eight Virtues of Britannia. As such, besides the pilgrimage to the shrines of the Eight Virtues, almost every action you took in the game was judged by its own karma system. Fighting thieves, bandits, and monsters would raise your valor, while letting animals like snakes escape would raise your compassion, and so on. The shopkeeper was a test of the player's honesty.
I attended two Distant Worlds concerts, one in St. Louis, and one in Omaha where I got to meet Nobuo Uematsu and have him sign my FFIX cover art. In the one in St. Louis, Susan Calloway performed the opera song that Celes sings in FFVI.
