I've also recently had four games that "exploded" and were never finished b/c of one thing or another that happened to the host. The worst case was
Fearsome Legions, in which the host Zachariah simply vanished at the most exciting moment in the game.
No offense intended for the possible great hosts out there but I've since learned to trust only llamaserver and Pasha. Mostly b/c my personal experience with some specific other hosts was bad (i.e. exploded games).
I think the MP community needs to have a hosts hall of fame (and shame) where hosts are measured by the number of games they actually hosted to the end. The hall should be used to help players make an educated decision regarding which host they'll entrust with their valuable time and effort playing a dominions game. The hall should by no means be used to flame or slander hosts. The hosts are volunteering their time for the benefit of players and IMO should be respected for that.
