Gamedaily writes, don't play these games, the eleven controversial classics that may be hazardous to your health.
1) Mortal Kombat
Mortal Kombat stands out as one of the most recognizable games around, thanks to its over-the-top blood splatter and brutal fatalities that have characters ripping out each other's spines. This ultra-violent fighter eventually led to the creation of the Entertainment Software Rating Board (ESRB).
2) Grand Theft Auto Series
Rockstar's open-ended crime simulator always draws attention, such as the public getting fired up over the "Kill All Haitians" graffiti found in Vice City and the Hot Coffee hack unlocking a secret sex game in San Andreas.
Rockstar decided to develop a game that would really give them something to shout about. In the flavor of high gore films like Saw and Hostel, the Manhunt games follow a killer that finds creative ways to use everyday objects as weapons of mass execution.
It has been accused of being a combat training program used by the military and a game that helped inspire the Columbine Massacre.
5) Night Trap
The game is cited as primary factor for the creation of the ESRB.
Featuring loads of gore and violence including a rape scene that uses full-motion video, the game was banned in Australia and Germany, while major U.S. retailers refused to carry it.
This game from 1996, which features full-motion video, has a list of offenses a mile long.
8) Mass Effect
It gained its infamy from a short and relatively tame alien lesbian sex scene.
9) Thrill Kill
Thrill Kill, a game that features characters that resemble marionettes maiming each other in four-player bloody combat, barely had time to stir controversy.
10) Hitman: Blood Money
Controversy for a game that features a bald, bar-coded assassin pursuing the perfect kills using various instruments comes from a completely unexpected place.
11) Elder Scrolls IV: Oblivion
A hack let users remove the generic clothing from the models, essentially allowing female avatars to go topless. The ESRB responded by upgrading the game's rating from Mature to Adults Only until a subsequent patch fixed the problem.
