Yey! This is a bit different from my One Word Story thing, but its kewl.
Here's an example:
P1: THEME: Explosions
So the thing is one person says a theme then other people say words to fit the theme. Then after the theme has 10 words under it, the next person says a new theme. For every comment there can only be one word (Besides the theme of course). The theme can be anything. Games, weapons, or just anything. Okay I'll get us started.
THEME: Time Machine
