According to Ubisoft producer Sebastien Puel, the Assassin's Creed 2 team has now ballooned to the size of a small army, with 450 employees devoted to the single title.
"The team's size for the second title of Assassin's Creed 2 is about three times the size of the team of the first game," said Puel to Nowgamer. Or, put another way, it is 225 times the size of the World of Goo team.
Puel noted that the team had "thousands of ideas" that they couldn't fit into the original game, but which are now being incorporated into the sequel.
Assassin's Creed 2, set to take place in the renaissance era, is scheduled for a holiday release this year on "all current-generation platforms."
