Role-playing games. We played Shadowrun for about 20 years. That's a near-future dystopian cyberpunk thing. Then we started D&D. Classic generic fantasy swords and sorcery. Too simplistic for my tastes, but it's easy. We've been doing that for a couple three years. Now we're taking a break from that, for the summer, and doing Twilight 2000. Post-WWIII para-military. Not my preference, but hopefully it will be interesting. Over the years, we've also taken breaks from the above for Runequest (fantasy) and World of Darkness - either Vampires or Hunters. The Hunters campaign was one of my favorites, but our GM moved away.
