Everyone seems to be having fun with their personal nightmare scenarios, so I'll try and be truly melancholic and forsee how the game most likely could be screwed up on the actual disc.
- Make aggressively tedious side objectives mandatory towards story completion, i.e. mineral scan X number of planets for narrative-necessary ship update
- Erase all playability for any/all paid DLC characters
- Stretch linear fire fights out even further, reducing dialogue and narrative points to the level opening and closing
- Limit ramifications of carry-over decisions from 'Mass Effect' 1 and 2
- Reduce player choice in the narrative to aesthetic character changes and cut/paste level swaps
- Expand customization options in the wrong direction: reducing weapon outfit and armor specifications while offering more armor color options and statistically useless paid DLC weapons.
- Continue showing no females of any species besides human, asari, and the partially hidden krogan seen in the E3 demo
- Adding more Paragon/Renegade "Press Left Trigger for Action" moments
....I'm depressed now.
