Vantaggi
Ubisoft Singapore has, in the past, collaborated with other studios to create AAA games like the Assassin's Creed franchise. Great learning experience working on AAA titles.
Svantaggi
The politics are incredible. Your skills account for 10% of your performance during the yearly review. The remaining 90% is dependent on who you are friendly with and who hates you. If a manager in the studio (not necessarily your manager) does not like you, he will find all sorts of excuses to have you fired. He will try to convince other managers that you are difficult to work with and if a majority of them speak out against you, you're out. On the flip side, if you're best buddies with your manager, he can find reasons to rally the other managers to his side and give you a promotion. Some have been promoted this way.
