Hmm. Our Seeing In The New Year gaming session is always an unusual one, where everyone takes a turn GMing a scenario they make up themselves, using whatever system they prefer, lasting between one and two hours. So last weekend I played:
GURPS
D&D 4e
Traveller
Heroquest
Twilight 2000
I GMed:
Paranoia.
Nothing quite hit the heights of one of last years games, where the players were trainee paladins trying to organise a annual holiday party for the orphanage without any help from their absent leaders while the cook was off sick, but several fun games were played. And five troubleshooters lost eleven clones.
