Selling t-rated and m-rated versions of games

I personally think that if companies that made rated m games for blood/gore/strong language, released t-rated versions of the games alongside the m rated games, they would make more money. If they did this, it would open up to a wider audience and sell more games. along with that, the online should have an option to play with players from the t or m rated games so you don't have little screaming 12 year olds playing with you. this is just my opinion though.
