I don't about you but I think this is cool. A kickstarter to make dice specifically for casting magic missile. I know I pull out about 5 d4s and set them aside when refereeing my DnD games just so I can quickly roll them for the enemy magic user magic missile spells. Since the effect of the Magic Missile has remained relatively constant across multiple DND editions. So I can see this being handy. for a lot of DnD Fans regardless of edition preference.
To me the Old School Renaissance is not about playing a particular set of rules in a particular way, the dungeon crawl. It is about going back to the roots of our hobby and seeing what we could do differently. What avenues were not explored because of the commercial and personal interests of the game designers of the time.
What are RPGs?
A game where the players play individual characters interacting with a setting with their actions adjudicated by a human referee.
Rules are an aide to help the referee adjudicate actions and to help the players interact with the setting.
Dice are used to inject uncertainty which make a tabletop RPG campaign more interesting than "Let's Pretend".
The only thing a player needs to do to roleplay a character is to act if he or she was really there in the setting in that situation.
