Its amazingly fun and good for at least 5 up!
Splatoon 2 is a very good game and there is not really much violence, consumerism (accept for paid DLC which is optional) Not at all any sexual content, swearing, drinking/drugs/smoking, you don't really have to worry about the safety and privacy and there aren't any good "role models" or "great messages" People might complain about the art in the square (main spawn area) or one of the character's clothing but 1, (you can disable art by following these steps, 1. Open your menu with X, 2. Go to the "Options" or "Settings" tab. 3. Go to "other" 4. click off on posts. If you don't want your kids playing the online multiplayer or don't want to pay for Switch online every year or 3 months you can just get them the Octo Expansion and they will have 2 great offline single player modes to play! Overall this game is really good and doesn't deserve all the negative reviews because of what content is hardly even part of the full game!
