I enjoy BL games too, I really do — they have their own charm, emotional intensity, and dynamics that I genuinely appreciate. But if I had to choose just one genre to stick with for the rest of my life, I'd still pick otome games.
I think it's because otome just feels like "home" to me. It's the genre I've spent the most time with, the one that shaped my tastes, and the one that gives me the most comfort. There's something about experiencing romance from the MC's perspective — watching multiple different relationships unfold, seeing how each route changes the tone and emotional trajectory of the story — that never really gets old for me.
So yeah, even though I like BL, if I had to commit to one forever, it would be otome without hesitation.
