I don't understand all of the complaining about Mewtwo. Let's put it this way:
Which would you prefer?
Mewtwo only being available to those who buy both versions (which might not even be the situation we are in),
or
Mewtwo not existing?
I think the answer is obvious. There is absolutely nothing wrong with companies rewarding their customers for supporting them well.
