I'm betting English isn't your first language.
Either that or you decided to be lazy. If you are trying to get people to play a rpg shouldn't it be more like "You play as (mc name) you are tasked with saving the world against the five border bosses, travel around the world seeking to destroy them and unite a world, while bringing peace to it." ? Or did you think people who just "get it"? You should have at least used a translation tool to see how much of what you said made any sense.
