Trophies are stupid anyway. There is no incentive on getting them. Remember the old arcades where they had games like the bulldozer coin games, or the skeeball game where the tickets could be earned and then swapped for stupid trinkets?
Well why not do that with trophies and achievements? Why not give the player an incentive to getting those? Maybe some USEFUL DLC for games (no garbage avatars or useless backgrounds or themes), or maybe some store credit towards a digital game? Do this..then trophies are useful. Might even just call'em tickets at that point.
