Yeah. Half of the people probably ended being disapointed by LoS2, considering the shitty ending and reviews.
I love anedoctal evidence.
EDIT: BTW, it isn't really anedoctal, it's obvious that some people didn't like the first game and wouldn't buy the second. Simple logic. We don't know how many, but seeing how LoS2 flopped, seems like it was many.
