I love seeing old dudes with fanny packs arguing with each other about what "old-school RPG" means. The answer is right in front of them. It's at their game tables. It's in their recorded Google+ Hangout sessions. It's probably a huge reason as to why very few women even participate in such games. It's because these same dudes all play their role-playing games like a CLUE board game.
That is what "old-school RPG" means.
