WC: There are three constants in both the film and gaming industries and that is quality, lack of quality and sequels. Anything will acquire a sequel so long as it shifts enough unit/tickets the first time around irrespective of quality. Whether these things deserve sequels or not is entirely subjective, but they’ll likely get one anyway if someone feels there are a couple of dollars to be made. There are plenty of films and games that justify revisiting in sequel form and then more than a few which just change a detail here or a control option there, repackage themselves and shout about how awesome they are.
But possibly the most annoying combination in the world comes when a great game or film gets a lousy sequel.
