RPG stands for “Role Playing Game.” It’s a game in which you take on a role of a character, in a world which might be very similar to your own or vastly different. The idea is that your character is participating in a story. A story you get to be a part of.
So we need a character. And we’ll want to describe that character. Is this character young or old? Male or female? Does he tower over members of his acquaintance? Do they tower over him? And most importantly, how many dice do I get to roll for damage when I land a double-critical with my Greatsword of Overwhelming Munchkinism that technically cost more than I told the GM I paid for it?
