Playing Assassin's Creed 2, gamers soon discovered that sequences 12 and 13 are missing without reasonable justification. A few days after the game's launch, Ubisoft announced its plans to release them as a DLC (Downloadable Content), feeding fans' skepticism that they were yanked off the game in order to be released later for money.

Turns out, Assassin's Creed fans were right. The sequences were originally meant to be part of the game, but Ubisoft decided to nix them off and sell them separately as DLC.

"I felt that, 'Okay, there were too many things to do and to finish,'" creative director Patrice Desilets justified the decision. "So we said, 'let's take a portion of the game that was planned and we'll give it in as DLC.' We'll remove some stress to the team while giving more to fans and people who like Assassin's Creed."

"I think we gave them so much content that they cannot say that we owe them, that we didn't give them a lot for their 60 bucks."

Desilets also admitted removing the ability to replay any mission because they didn't have enough time to test it properly. This feature, however, may be patched "eventually".

Assassin's Creed 2 has seen positive reception, but it is criticized for employing boring tricks –such as lengthy and un-skipable cut scenes - to expand gameplay time artificially. The game is also criticized for its repetitiveness and lack of variety in missions.
