Mild violence
There is mild violence in most computer games. Do you let them play Mario based games where you're encouraged to shoot characters with fireballs, push them off ledges and smash into them with cars? Zelda? Star Wars?
What about Minecraft where children are encouraged to stab villagers with swords and pickaxes and slaughter sweet looking animals by bludgeoning them to death? Fighting hoardes of zombies and other enemies?
If you let your children play these games, why not Fortnite? It's far less violent than Minecraft.
Also, it is not similar to Cod at all. Yes they both involve shooting others, as do many games. COD is very realistic and so are the deaths. The guns are real, there is blood. Some of the games are about real events in real places with realistic human people. There is in game bad language and very graphic content.
Fortnite has cartoon graphics with different characters, is played on a cartoon map which is the same every time. Yes you shoot people as you do in many children's games but there is no blood, you don't 'die', no bad language or graphic content and everything is aimed at children.
The games are worlds apart.
Have you played both , Nearlythesummer, to make that comparison?
