Well...
Sex.. I'm okay with the occaisional artistic nude woman but I would never want to watch something like a woman sucking on a (samurai sword), and I think I'm going into too much detail so I'll stop. Meanwhile I wonder why the heck all this has to be involved in video games..
Violence.. I'm okay with the basic Tekken style martial arts ass kicking, even some blood, but if it's whatever the hecks going on in Grand Theft Auto then, naaaaah!! Not interested!!
I do have "State of Emergency", which I really regret buying and I'm hoping someday I'm gonna trade that for something better.
