I think that, on the game's comment walls, there should be the choice to reply directly to people's comments. whenever people say they agree, they have to say "...To so and so, I totally agree with you!" And then the comment moves down and you don't know who that was. Also, if you want to edit something you said, it could be like this. "...And it's too loud" (first comment)"The game is fun, but [forgot what they were saying]"
"...And it's too loud. This game is fun, but." That's why I think adding replies to comments would be good, especially for the new AG 3.0.
I have an idea. I think that when you get a comment, a little thingie on the top bar (like where it shows your username) would give u a little notification signal. So you could see it and go "hey, I got a comment!" Or something like that.
