This is a very difficult question, but if I had to choose only one for the rest of my life, I would choose otome games. This is because there are overwhelmingly more stories I like and more games to play in the otome genre. However, there are also many BL games that I have a deep emotional attachment to, so I'd probably start agonizing over my choice again as soon as I made it. I'll stop thinking about it. I would choose otome games!!
