The problem I think is not so much that people play easy games, it's when people who play these games and have 500 plus Platinums brag about how many they have and say things like "A platinum is a platinum"
I personally think Sony should "devalue" the points system for super easy games(Ratalaika games for example) so that a platinum is worth less points on that game that it is for say something like Red dead 2 or even remove Platinums entirely from these types of games
I know there are many people who really get upset about this topic but at the end of the day people can play whatever they want and it doesn't really affect me or the games I play instead. I enjoy long and fairly difficult platinums but it's not to say I haven't played and earned a few of these easy Platinums myself but I definitely feel games such as Red dead 1 and 2, GTA V, Assassins Odyssey and Valhalla etc have given me more satisfaction from their Platinums than any easy games have
