Thank you for the ICB mentions
As a player, I really enjoyed The Mole [Rory and Benjamin, perhaps Marc hosted one too?], Survivor [various hosts, Marc, LemonJam, Reece and DTM from what I recall] and Darkwood Isle [Dezzy]. Oh and the pub quiz is always fun, and GypsyGoth/Z/others did great jobs with it but I think Jamie89 knocked it out of the park.
As a host, I most enjoyed running Eurovision but at the same time enjoyed the creativity put into ICB (it was just a lot more stressful and time-consuming than Eurovision ever was). Elimination was my first "major game" hosted and it showed me the ropes.
As an observer, T* did a really good job with Revolution but I think I only took part as a guest judge once.
