this could probably work but some games just dont deserve an age rating, such as:
NFS
Minecraft
Roblox
Any Car Game Really
Farming Simulator
The Uncharted Series
Ratchet and Clank
and any other childrens games.


Most of the games ive listed here are childrens games with ratings ranging from 3 to 12.
These games dont really deserve an age rating considering theres no usage of irl money, drug abuse being shown, excessive violence, jumpscares etc.

Of course there are some games that fo deserve an age rating but they shouldnt exactly be HEAVILY reinforced (such as them having a law about video game age ratings).
Some games are too gory for younger people and therefore i approve of them having an age requirement (but as ive said before the age ratings shouldnt be that heavily reinforced), maybe the rules should just be tightened, like a public service announcement warning parents about the dangers of violent video games.

tl;dr minecraft is for kids and is ok, mortal kombat is not. Rules are nice
