More realistic women.
Also games that involve physically harming others (be they other humans, aliens, monsters, robots, synthetics, or something else that you can kill, destroy, mangle, knock out, turn into a flopping ragdoll) is the majority of gaming. This is especially true for the mainstream gaming industry. Simple examples are at Halo, Call of Duty, Battlefield, Final Fantasy, Skyrim, Super Smash Bros., they all involve defeating something or someone. There are of course the exception to the rule. The Sims, Animal Crossing, and the many stupidly popular facebook games out there that play a more casual role because they were made to appeal to a more casual audience. I'm not sure on the Eastern gaming industry besides what Nintendo throws out from under their hats, but I don't know if a game like Persona 4 fits under the objective to defeat something or someone or if it fits under casual. Either way it is easy to market violence which is why most games do it. Even MapleStory is mostly involving killing something to gain something (kill monsters to gain EXP, money and rare items). It is a violent game even if it is light-hearted compared to other games. If you want a truly brutal game there are plenty others out there. Besides that it is incredibly difficult to make a main game hit the market that isn't something that involves physical violence. Fighting is easier to market.
