I ran one of these on the Resident Evil boards, and it's fairly successful. The basic idea is that you post one or two sentences about little things in ME3 that annoyed you. Try to avoid replying to someone else, just like their post if you agree. I hate how all of the multiplayer races and Shepard share animations. I hate how the characters don't change outfits from ME2. Do they have automatic laundry? I hate how all the women got implants. Ladies, boobs aren't laser shields. I hate how they re-use conversation animations from ME1 and 2, and that they're awful. I hate how only the Predator gets a different reload, but the rest use the old one. Why?
