I was just thinking. Should game developers just make sequels as a DLC instead of a disk. Lets take everyone's favorite game series Call of Duty for example. Now let's take CoD:Ghost and let's say that instead of Activation make CoD: Ghost 2 as a disk instead its just a DLC and adds more missions to the single player campaign, more maps and weapons for the mutiplayer while taking in account the previous stuff from the first game, heck even the DLC's from the first game can work on the sequel since all it would do is just add stuff to the old game. since gaming consoles have more memory then what you can do with I think this will save money on making disk for sequels.
