Gamers are generally decently excitable, especially when it comes to our games. The stereotype that a gamer will talk your head off about their favorite character does have some grounding in truth, after all. So, my question for you today is what makes you geek out about your games? What gets you so excited that you'll find yourself telling people who maybe don't even game about it?
For me, it is generally when I manage to pull something clever off as a GM. Things like the Shuten Doji fight in Shadowrun that I posted about yesterday. I love it because it is fun as a narrative, and as a game, and also as just something silly and neat. What about you though? What kinds of things just make you want to tell people about what happens in your game?
