im 17 too, turned 17 recently. i dont see why it would be a big deal if i played this game.
its not like when you turn 18 you suddenly gain +5 maturity.
but i know some other guys that dont even use the speech options on fallout games. they take the 13 year old path and just kill all the npc and take their weapons.
hell when i was 13 i had already beaten fallout 1 and 2. got the good ending in most settlments. ( i kept replaying to trying to get good broken hills ending, turned out there wasnt one)
what im saying is even when i was that young i was still mature enough to play games like this.
ps. super excited for the its always sunny season premiere tonight
