Been on my mind for a very long time and figured I'd throw it up in the forums for discussion. I do not think DLC trophies should count towards your completion percentage for a game. I believe it is not fair for those that 1) do not have money to buy the DLC, and 2) more importantly, for those that choose not to buy the DLC nor want to carry on with the game, should not have to suffer their completion % from going down.
Overall, I really could care less.........we don't get prizes or money etc for trophies but as an avid gamer who does like to try and collect all trophies for my games, I think it's dumb that I nor anyone should have to suffer getting snubbed with stupid DLC content trophies. I do believe that if someone should purchase the DLC, then it should go towards their completion status of the game. I know it would be difficult and all that to separate, but in today's world and with the new technology, I don't see how it can be that difficult. Time consuming for them, yes, but hey, their making lots of money.
