Alrighty, folks, I made a promise, and here I am, following up on that.
So, in Junior Year of high school(that is to say, in the spring of 2015), I ran a D&D game with some friends of mine. First problem: of the five I invited, only three showed up. Problem two: Of the three, only one had played D&D before, and he played ridiculous clownshoes D&D and his first thought in character creation was "I wanna be an evil character."
No. No, fuck that. I don't let people play evil characters in my games. Why? Because evil characters are always disruptive. If you have a paladin, or a good-aligned cleric(spoiler: you probably will), then the evil character is going to make a rift in the party. A rift in the party is never good. Don't do it. Don't bring an evil character to the table if we're playing D&D.
Anyway, I told him that no, he wasn't allowed to play an evil character, nor was he allowed to play chaotic neutral(which is almost as bad). So instead he made a true neutral character, who then proceeded to do awful shit.
I don't remember all the details, but I do remember that their first fight was in a tavern against a bear that came through the wall, which they lost. The half-orc barbarian tried to break down a door, and rolled a 1, which I ruled was him trying to punch the door open, which resulted in him breaking his hand and making the door harder to open(We were laughing a lot at that). The elven ranger climbed up a tree because he thought there were kobolds(there weren't, and I never said there were). He then jumped /out/ of said tree, and tried to get the barbarian to catch him. I told them both to roll a Dexterity check, and if they added up to twenty or more, the elf wouldn't take damage.
The elf took damage.
And, near the end of the session, they said "fuck this" and went back to the bar, the elf picked a fight with a sailor, got his ass kicked, and the party joined the sailor's crew, which was smuggling porn(I gave up long before that point).
