No I don't really care. I stopped caring about the AC series with AC 3, which was so lifeless and bland it gave me a digital lobotomy.
I'm glad that they are putting some diversity in their protagonists, just on the standpoint of diversity being a good thing in my opinion, but it's not going to make me buy the game.
The awesome pirate sailing goodness of AC: Black Flag wasn't enough to make me give Ubisoft anymore of my money.
They have shitty business practices, and have a significant level of contempt for their customer base. So, I choose to not be a part of their customer base as a result.
They could make every hero from this point forward be a different ethnicity, and flip the genders all the time, and I still wouldn't buy anymore of their products. Which does sadden me a bit, because I think from a gameplay standpoint, they make some very fun games. But there are a lot of things in this world that I like, but don't like the people who make them, or what they stand for, so I don't buy their products. Ubisoft is just the most recent addition to that list.
