First time was Assassin, the second was Rider.

The first time was mostly CK's fault, because he forgot to update Teh, myself, and our friend GoL for like two weeks, leaving us strnded in the Church. The second time I actually got to fight someone, but the background plot advanced too quickly and our fight had to end before I got in the kill, and the game ended rather abruptly shortly thereafter.

Which was a shame, because Rider was totally badass.
