I'm not watching that as I'm not too far in MGSV and do NOT want to view spoilers and once again, Metal Gear Solid V is rated R18+. If we did not have that rating, then it would either be banned, or released over here with a MA15+ rating, which would have content censored or outright removed (look up Left 4 Dead 2. We couldn't even have zombies on fire).

If one country says no to playable children (PvP could be seen as "harm children to earn points" or some silly nonsense like that), then that means everyone will not get playable children.
