If the industry thinks implementing local multiplayer is bad for business then why don't they instead of having no local multi-player at all, they could lock the split-screen feature and unlock it to users that have their own individual licence to the game, this then means you could have 4 people sign in to a single device that own a licence of that game. Also then the developers can make statistical analysis to see how many people are playing on the same device to find out how popular split-screen really is, local multi-play definitely adds so much replay value but how can they know people are using it currently, i guess with xbox live its possible. I like the idea of having your progression saved to an account with achievements along with this.
