User blog comment:The Forgotten Fragment/Black Flag too soon?/@comment-1715386-20130301041652
1. It's not just Ubisoft Montreal developing games, various Ubisoft developers are coming together to produce AC games. 2. The more familiar with the engine you are, the faster you can finish your work. The team working on the naval sim is most likely the team that developed it in the first place. It's expected that they'd crank out a naval AC the fastest. Also, Ubisoft uses autodesk software and they continually advertise the ease and speed that allows Ubisoft to quickly develop things. 3. After that, it's just working on the story/plot/characters. At least one month ago Black Flag was conceived. AT LEAST. 4. Basically it boils down to they finished the game they envisioned within a time frame and they're not gonna sit on it for a couple years just to make the release dates further apart.
