Arrh, to be sure.
To add a bit more detail, I played Mouse Guard in the morning, LotR variant run by Rick Evans. None of the four of us had played it before and two had German as their first language. I think Rich* did a first rate job as GM, not only in explaining the game but also running it. I turned evil halfway through and started a war between Gondor and Rohan.
In the afternoon, I ran Mutant City Blues for the first time and it seemed to go OK.
Then we played Alien Disco Squad, to my shame.
*Rick confusingly had Rich on his badge so I'm not sure.
