Red sand Hanar orgy here we come.
Can I just admit that I've always hated the focus people have on sex and nudity when it comes to Mass Effect games?
Always comes off creepy to me.
Honestly I'd be perfectly happy if the game had absolutely no sex scenes.
I feel pretty similar to be honest, but liken it to a BioWare problem rather than the simple fact there's sex and nudity in the game. Waifu/shipping culture in general come across as oddly possessive and creepy. Romances can comfortably be a part of any engaging narrative arc, but sometimes BioWare's feel excessively pandering and fail to develop in an organic way.
They're getting better with Mass Effect though, I think, mainly due to stronger character dynamics. Inquisition has some utterly atrocious romance dialogue, with some lines seemingly penned by someone who's never actually had romantic relations.
I do wish the romance arcs were a bit more complicated though, and if it were me writing them I'd make some characters just totally unwilling to commit to a relationship even if you've slept with them. Character writing in interactive games, especially RPGs, is always at its strongest to me when the NPCs don't exist entirely to serve the player. Romance in games unfortunately is so much that; you basically get to pick from your harem who you want and if you click the right dialogue you're
guaranteed to get them.
Add in some heartbreak with a dash of tragedy. Don't always give the player exactly what they want. Get them dumped. Have them chase dead ends. Imbue characters with the illusion of autonomy and individuality.
