Fortunately/Unfortunately
I like this game because you can make up circumstancial situations. Like, someone says something fortunate or good about something that happened, then the next poster says something unfortunate about it as well. For example:
1st: Fortunately he didn't get hit by the car.
2nd: Unfortunately the car hit another car down the road.
3rd: Fortunately no one was hurt.
4th: Unfortunately the car driver blamed him for the accident.
And so on and so forth, you link everything that happens to something else and mix it up a little, to make it a little more interesting. You can also add in anyone from the board just because and mix up the situation too. I'll let you guys start off to get something good going on.
