Not really the last 3 main entries added new mechanics which are the themes of the game, Tri had underwater battles and hunts, 4 added vertical elements to hunts and Generations/X added the style system. These were big changes that impact design so would not be easy to add as DLC. |
I think he's referring to the fact that each main entry ALSO had another game released within 12 months as an add-on extra that was put at full price.
