Duke Nukem or Prostitution games?

According to Kotakuit seems like Duke Nukem Forever will actually launch. This year. Seriously.
Wouldn't it be awesome if this game launched, sold 10 million copies and was the best shooter ever? Every publisher would have to rethink their strategies and developers worldwide would be stunned.

A friend of mine was very recently made Junior Game Designer at Avalanche, I was talking to him today when he mentioned a discussion he was having on games about difficult subjects. Really difficult. He was playing with the idea of creating a game about prostitution or pedophilia. He was struggling with the problem that he's learned that games are supposed to be fun. And making prostitution or pedophilia fun might not be everyones cup of tea.

I've been having thoughts about this for some time and I think that Raph Koster seems to be on the same track as me. Games don't need to be fun. Most games on the market aren't fun, think about gears of war or Mass Effect. They aren't fun, they are entertaining for sure, but not fun exactly.
Maybe it's because we still use the name games that we've narrowed our scope to just fun, maybe we should call it interactive entertainment instead. The term sums up our industry a lot better, Brain training is not fun, but it is entertaining.
Games, or interactive entertainment, should be engaging.

And nothing is stopping the most heinous acts from becoming engaging, give a player a perfect control and the order to perform a gruesome act they will quite possibly do it. But they will quite possibly also experience completely different feelings than fun. Hopefully at least.
But to let this happen we need to let go of all the bells and whistles we are using to create fun today. Maybe rape should not be awarded with points. Maybe it shouldn't be awarded at all. But should we shy away from letting the player do it? Certainly not. We are after all, trying to engage peoples feelings and thoughts through our art, and they must perform the actions.

This is interactive entertainment after all!
