I think its a bunch of BS that people think kids playing M games causes them to go shooting up schools and mutiliating cats...
BUT after seeing YOUR post and how you are against all that stuff (ie six, drugs, language, blood, nudity, ect) Im thinking you might have a tad bit of growing up to do before playing this game...considering it consists of ALL that stuff...And the fact that you will be taking steps to change the game to cater to your youthful eyes, Id say wait..I was quite a different 14 year old than you are let me tell you, hah.
Its good tho to see a kid who actually isnt all [censored] up and having six with all their classmates like you see 10 year olds doing nowadays...Its sick
when I was your age all i wanted were M games because they always seemed to be 100x more fun than the lame E games...
In the end its your call but since you ARE such a good kid and im sure they know that, I think you can pretty easily convince them...(now im contradicting what I said earlier..lol o well)
And unless they are going to be watching over your shoulder while you play the whole time...They probably wont see the bad stuff (besides the violence)
I think the main stuff that might turn them off of it is the crucifixions, cannibalism, and drugs...So id say try to not let them see that and you should be cool :thumbsup:
P.s. are you in High School yet?
