Violent video games are an easy sale. If you shoot people, or beat them up, or anything like that, almost every 13 year old boy will want it.

However, if the game involves any thinking, or non-violent stuff, those same kids won't even try it. Sex and violence means big money.

Examples-

"Call Of Duty: Excuse To Shoot Stuff" = Instant hit.

"Sim City: Make People Happy" = Slow Sales.

"Street Fighter 10: Blood & Boobs Edition" = Line Ups around the block.

"Test Drive HD: Quiet Sunday Drive" = 10 people bought it.

For the record - I think First Person Shooters are a dime a dozen, and I only like playing Grand Theft Auto because of the driving.
