Pros
There are some great people in the North American office, many of whom have strong backgrounds in game industry marketing. There is a good balance of experience and fresh ideas. Has weathered the economic storm relatively well and hasn't had to lay off employees. Ubisoft prioritizes keeping its talent and does what it can to avoid layoffs. The upper management in North America does their best to foster good company culture and new ideas despite what seems like a frustrating lack of room to grow for those upper executives.
Kontras
There is some tension between North American and EMEA operations. As the company grows larger, they are becoming more risk averse and rely on sequels. Anyone who isn't French probably doesn't have a great chance of reaching the highest levels in the company. Seemingly somewhat stingy with compensation.
