Except they wouldn't be doing nothing. They would have been working on AC3.

Granted, you are probably right that ACB and ACR helped them flesh out some ideas for AC3.

Developing Ezio's character? Why? The major development of his character takes place in AC2. That's why I love that game. ACB and ACR did VERY little to develop Ezio's character IMO. He was already a Master Assassin/Mentor, he had already found his identity, so there wasn't much left to develop.

Yes, Cristina died, and Ubisoft saw it fit to give him a wife, but the romantic relationship between Ezio and Sofia was very weak. I didn't feel that spark of romance and love. It was like the game was forcing us to believe Ezio and Sofia were in love. Whereas in the Cristina missions in ACB, it was much stronger, and with less memories, too.

Overall, ACB and ACR did little to develop Ezio's character.
