RS should have a sequel, there's so much hype about and every single one of the reviews i've read from ppl that went to E3 said it was great. Like Napalmbrain said, the majority of succesful games get a sequel, which in this case u couldn't really say considering it's not even playable but it will have to have a sequel. I mean it just sounds so good, it would be unbelievable if it didn't have a sequel. The only thing that would prevent it from doing well is if the controlls were a little shaky and the gameplay wasn't good(somehow).
There better be a Red Steel 2!!!!
