I play to be immersed. I can't play any game that I can't relate to. Daily life and male MC is a must for me. I have tried games with sci-fi/fantasy settings, but I can't get in to them.
Also, I prefer games with slower build-ups and interesting stories.
Overall, I'm pretty vanilla. My fetishes are stockings, brunettes, POV cowgirl and young woman with 30-40 y.o. man.
