Sorry if there's already something like this, but here's a new game!
How to play:
Just put out a trivia or fact about something! You can put a topic (general or specific) at the end of your post, and the next person would have to give a fact for that category, or just write "free" and let the facts freeform!
Example:
Person 1: <fact>, animals!
Person 2: <animal related fact>, free!
Person 3: <fact>, bears!
And so on.
First topic will be freeform!
