We all know that sequels are mostly what games are now thesedays, with some major Playstation franchises now going on thier 7th to more incarnation(Tomb Raider). When is a sequel unwelcome? What defines too many sequels? For me I used to hate sequels, but now realize that some of my favorite games of all time were sequels(Super Metroid, Link to the Past, Super Mario 3). What makes a good sequel? What makes a bad one?
