It all depends really. A sequel, or even trilogy works. However churning out spinoff after spinoff that increasingly has less to do with the initial concept save for Easter egg or shout out type things that exist solely to go 'hey look, see, I'm a sequel!' (phantasy star universe/PS0 I'm looking at YOU). In these instances developers should take the ideas they thing might be cool for brand x or y and figure out how to retool it so it can stand on its own, because many games would be really good IF they wern't tied to a brand that theyr'e plainly not taking in a direction the fanbase wants.
Sports games is something of a loophole in this because you have to keep up with current rosters. However that's a whole 'nother ball o wax that I cannot adiquitly go into.
