On this date, fifty years ago, Alan B. Shepard was launched in Freedom 7 for the first US flight into space. It was a 15 minute sub-orbital flight using the first version of the Mercury Capsule and a Redstone Rocket. The only glitch on the flight was the confirmation light for the automatic jettison of the retro-rockets didn't come until Shepard pressed the button manually.
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.
