Here are some that come to my head, I'll post more later probably:
Mandalorian's insanity in Sherwood Forest resulting in the 75 page day one and his eventual lynch.
TWO's post restriction for me in his Bar Room Mafia and everyone thinking I was just permanently drunk all the time. ]
KiwiTaker and his dangerous explosives!
LSU Tiger Josh vs AnarkistsDream in Sherwood, a classic argument if ever there was one!
The old wicked vs Mandalorian fights, they were always great.
Kwanton's sanity being put into question in one of Freezie's Harry Potter games before Freezie realised he had sent two of the same role out!
NES getting lynched day one in every single mafia game on the site for a few months.
Mandy getting modkilled in Fircoal's Confusion Paranoia Mafia Game for his naughty stunt!

Mine and Koesen's duel in NJO mafia, having 29 other people to pick who we thought our on game rival was in day one, we both completely lucked out and picked each other, but I picked first so I won.

Tonka always being pro-town
Wicked always being scum
