So let's just include more generic human shooters because they are Sony and not because they will actually be different or interesting to the game?
That's like let's ruin the game for the sake of glorifying franchises instead of making a fun game. Emmett though generic has at least a good "build & battle" system, otherwise if he was jsut using his guns again it would be a terrible choice to include him. The only reason is that we hope his build and battle will bring something new to the table or at the very least not be a generic gun slinger.
I don't see why people have problem with 3rd party characters if they can really be fun for the game and that it HAS to be a sony character even if that character is boring as hell to include in this game. They might be interesting in their own games no denying that but adding more characters to this game should be based on quality to the game not glory to the franchises.
