In DBZ Budokai, I'm pretty sure I've completed the story mode. There was some more scenes and battles from the show, as well as several amusing "what-if" scenarios. One where Vegeta becomes a Super Saiyan very early on, one where Goku and the rest are all defeated on Namek, and a third dream sequence of Cell's where he imagines what would happen if he absorbed Krillen instead of one of the androids.

In FFX-2, I explored the town of Kilika, which is totally rebuilt. There was a tiny bit of story stuff there, but no missions or anything yet. Next, I went to Luca, where the game's strange opening sequence (concert) is fully explained by Yuna in a playable flashback. There was a goofy mini-game which involved Yuna dressed in a Moogle Suit handing out balloons to people. I got a new job class for it though, I believe.

I also went through all the tutorials and glossaries to refresh myself with some stuff from the first game and learn more about the surprisingly complicated garment grid system. I was actually rewarded with an item for taking with the tutorial.
