Well I'm bored so I'll start a topic that we should all get some good laughs out of.
Your biggest failure ever. You may also include stupid mistakes and funny outcomes.
Here's one. We decided to play a game against Cthullu. Turn 5 opened our 6th gate and we got clobbered.
In our very next game we were playing Yoggy. Turn 4 opened our 6th gate. Naturally no one had a trophy so we all were instantly devoured.
The bad thing about the second game is the 3rd mythos card was "You may trade items with investigators w/out being on the same square as them" and we forgot to give the elder sign to the person in a gate. Also the person in the gate rolled to seal got 1 success so he started spending clue tokens. All 5 failed.
After this we decided not to draw an inicial mythos card to give us all one grace turn where we didn't have to worry about anything. At the time were weren't vewry happy though.
