Here you can post what you think would ruin the best RPS series ever. To me it would be activision puplishing it. They would start with a game that will dumb it down so much that the guys who complains that skyrim is dumb down would think skyrim is complex. (in other words alot) And start releasing a new one every year. And possibly add multiplayer to it. And ES would be a cash cow... Luckily that wont happen. Still what would ruin the TES to you?

Online multiplayer.

If the game lost it's open world, do anything style.
