Quoth Geek King
Hee. I was in a near-future, high-tech RPG campaign set in the year 2040. The GM specifically mentioned Metallica's "Fuel" and "Enter Sandman" being used to sell Caddys.
:-) I was in a futuristic RPG ages ago, our party win condition involved sticking external speakers on our spaceship and buzzing planets, forcing them to listen to Metalica.
(we also had a holodeck in the basement, the GM had no issues with that, but did claim we didn't have enough memory to run Doom on the shipboard computer... As I say, it was some time ago...)
