All of your comments show up to me as having a red username, where everyone else is blue. I'm in Voyager. Either your role is permanently showing in my app, or you've got something messed up with the settings. Maybe the shield means "Hide your mod status" and you've got it backwards?
As for the benevolent trust fund kid...you're only focusing on the good. Others are only focusing on the bad. Both are wrong. And I don't think getting into the exact ratio would be productive, lol
I do empathize with the challenges of trying to feel like part of a community while being "othered" like that. I think the best thing you could do is to not have your username be glowing red for everyone.
Whenever a mod comes in commenting with their mod colour turned on, it makes it look like the mod is implying "Whatever I'm saying here is more important than anyone else's comment because I'm a mod". Whether you intend it or not, that's how it can come across. And to anyone who has issues with authority (which will be a LOT of people here, lol), that's just putting a target on your back.
You can't change the comments that people post, but you can influence the kinds of replies you get.
There's a set story, but it's discovered. The world is wide open, and the player can go anywhere right at the start of the game. There's minimal railroading at any point.
Unless I misunderstood what you meant by emergent narrative. The progression through the game requires the player to learn what to do by interacting with aliens and also exploring a bit. There is an in-game hint system (an alien dialogue tree with prices), but there are often multiple solutions to each "problem". The player can even get through the game being good or evil -- whatever they choose!
The game plays very differently than ME, but you'll probably find the dialogue trees very familiar. And I think SC2 actually does them better than ME.
