Yeah, you know what you're in for, posting this here. But I agree.
-For the light side of things, I want the concepts of exploration and progress to be prominent. But I don't want it to be constantly shiny. While I don't want as much of 'brutal underworld' ME2 or 'constant war' ME3, I do want MEA to, perhaps even (relatively) suddenly, shock players with the truth that exploration and progress does not come without inevitable and disillusioning cost. While ME3 was 'You're going to lose something', I'd like MEA to be 'We're going to have to leave something behind/take something of others'. Expansion and colonization (even if just the start of it), and some of the nasty things that comes with it.
-Yes, I'd rather not have it so no matter what, I get to make the heroic speech and people follow me into the darkness. It would actually be so cool if I could have my character start to try to do it, but because of X factors, I get interrupted by competing voices, and I have to take another route (perhaps through personal convo, something behind the scenes) to make things work well enough to move on. A similar concept is when you're forced to resolve the Jack/Tali and Miranda/Legion conflict and you can do it there and look awesome, but if you fail it, you need to meet a character later in order to regain their Loyalty.
Basically, I don't want to know that I'm definitely going to be the kickass hero of all things at all big times. No longer a Commander, a Spectre, a Savior, a Shepard, I'd like a 'Pathfinder' to have relatively more of a 'weaving around' the politics of his..everyone's mission, and not have it as clearcut as the fight against the Reapers and the basic facts of 'If we don't do X, we die from Y." spurring people/factions into action. I wouldn't mind some characters going "Well so what? Who put you in charge and why does my agenda not matter as much?" and I'd like to even be able to agree that maybe their agenda really is better than what I've thought was the way to go.
Basically, lessen the hero worship. It can be a thing but it doesn't necessarily need to be as high as any other Bioware game of the last decade (except maybe DA2). Let my character breathe.
-I would not mind scars and more blood. Not a ton more though.
-Hell, I want First Contact War x100. Bring on the hate between peoples, and play the role (optional or not, I dunno) of the 'Council' (person) who gets things settled one way or another.
-I'm a gay male. I don't want every LI to be bi/story-sexual. While I don't want this all the time, I do value stories that involve or even (rarely) revolve around the character's orientation. I don't think it was done the most tactfully with characters like Sam (ME3) and Dorian (DAI), but as a thing, I sometimes like it, and stuff like that can't happen if every LI option goes for your PC no matter what. I was one of those supporting DAI for this over DA2.
I just want a couple options. Give me those couple options, and especially have both of them compelling, and great, I have my choice and inclusion and I'm happy and if people want more, they can have fun modding it in.
I was sad about KOTOR and JE (I didn't know about Sky until later).
I was annoyed by ME1, ME2, and kinda DAO (Zevran is not appealing..) and DA2 (neither were appealing though that's more of a general complaint).
But I was glad at ME3 and DAI, overall. But I considered them still more flawed than they could be.
So yeah, there's room for improvement in the next ME game, and I don't need everyone to be bi/gay/playersexual, but I DO want options, and I DO want inclusion as long as the creators are up for that. That's all. I'd have went for James but he wasn't an option and there was Kaidan and Steve. Got my options. Semi-compelling. I'm mostly happy.
EDIT: While I get the 'this isn't the real world so why care about realism' argument, I still don't enjoy the sense that I turn a corner and see homosexuality. Not homophobia, internal or external, but more an appreciation for statistics, where even if we stretch them, the very most homosexuals one will have in most settings is 1/4ish, if that. Imagine that there's a ship with even 8 LI paths, 4 of them male. I'd.. not raise a storm at it, but I'd laugh my ass off if all 4 of those males flirted with me/I can flirt with them to positive reception and reciprocation. I can take 1 and I'd appreciate 2 for the sake of having choice, but I don't really need more, that's all.
