Can you imagine the news stories if splatoon had voice chat and 8 year olds were being yelled at, called gay or groomed by gross old men.
This isn't a r16 game and it is a better experience keeping idiots from ruining my fun by allowing them to swear and troll me.
Half the games I play are full of players from non english speaking countries anyway, no voice chat means you don't segment players and make it international.
Are you being serious?
