Well the other difference with COD/FIFA is they're accepted as an annualized franchise so you never have to buy an "old game" whenever you purchase your PS4/XB1, there's a new version of that game available. GTA is just a freak of nature, I'm not sure if any conventional rules apply to that game, that's beyond evergreen, that's like some other category, there's never been a single title game like that in the history of the business (released one generation prior but becomes the best selling game of the next generation too).
