I think it would pee off a lot of poeople but in the end the video game industry would be so much more creative again like the 80's and early 90's. We would see more games like Okami, Shadow Of The Collosus, Zelda, Mario, the list goes on and on... I think most action games feature guns today and all play the same. Take the new Tomb Raider... Do we really need guns in it to make it good? Nope, she can use only her bow or something like that.
It won't happen but it would be cool to see the industry go 1 year without producing one game that featured guns in it's core gameplay.
Note: Most of my top games have guns in them this gen lol. So I'm not bashing it in any way or form. Just asking what would you do?
Quit gaming? Start playing new games out of your normal genre?
