When the gaming group I was with in 1974 started playing D&D, we immediately took on the persona of whatever character we were playing. We'd already been playing Chainmail and other miniatures games (and many, many wargames) and welcomed the new way to game. Acting the part, at least superficially around the table (without getting to our feet), was what we understood the game to mean by roleplaying, not just filling a tactical slot. In fact, it was more likely in those days that the tactical slots were not relegated to specific character classes but, rather, that things would switch around depending on who came up with the latest plan or scheme and who felt like stepping up for the tougher jobs, whatever those proved to be at the time.
