The genre of the games is not important. I cite CnC as it is an example of a franchise which in my opinion was ruined by EA's influence, based mainly from playing the RA games. EA have a knack of making things look pretty as the expense of substance, which hurt the RA games released under their watch.
It doesn't matter that the games are not simmilar (I shouldn't need to say this since it is obvious), my point is that if their involvement is more than just distribution then there is evidence from past games that this involvement might be harmful to the overall quality of the game.
