hey! i stumbled across this group and, as a rabid wargamer, thought i would drop in and give my two cents.
we have several house rules for Munchkin, because Munchkin is just to cool of a game not to have house rules. the simplest house rule concerns the supermunchkin and half-breed cards: simply, if you have two supermunckin cards you can have three classes; three supermunchkin cards you can have four classes. the same is true for half-breed. you can very easily become a third-breed or a fourth-breed.
another favorite house rule for Munchkin concerns the wannabe vampire. if a cleric chooses to make the wannabe vampire run away by saying "booga booga" he is required to stand on his chair, extend his arms above his head and say the words in the most haunting manner he can come up with. if the chair is unstable and will not support his standing weight, he is required to stand on the table.
in BANG! the first game you play you are required to say "in heaven there is no beer, that's why we drink it here" whenever you drink a beer to regain health. you are also required to say "i shot the sheriff but i did not shoot the deputy" the first time you shoot the sheriff. However, if you do either of these things more than three times, the other players have the right to glare at you and tell you what an idiot you are.
in another favorite game, Guillotine, (the Revolutionary card game where heads will role and you win by getting a head,) whenever the Bad Nun is turned face up and again when she looses her head, everyone playing the game is required to chant "Bad Nun! Bad Nun! Bad Nun!"
along the same lines, in Circus Maximus, the chariot racing game, whenever someone is trying to take out an opponents horses with his cart, as he is warming up the die roll, the other players (even the one being attacked) are required to chant "Alpo!"
in Vinci, you are required to refer to the little colored chits as "men." politically incorrect jokes about "the white men," "the black men," "the yellow men," or "the red men," are acceptable, but the first person who tries to work in "the blue men," or "the green men," gets a beating.
in Diplomacy you are encourage, though not required, to speak with the accent of the country you rule and to rename your country based on something else historical or personal, as long as it makes sense. this is how we get games of Diplomacy with The Byzantine Empire, The Scottish Realm, Prussia and Those Damn French.
in Napoleon in Europe, if you ever have a large army that lacks infantry, cavalry or artillery, the other players are expected to mock you.
in Warhammer, you are expected to mimic what the models are saying if they are moving into a place where they know they will be exposed to enemy fire, or when they are actually being fired upon. this rule does not usually apply if your units are human, but applies doubly if the units in question are goblins or if you are especially good at doing voices.
also in Warhammer, all goblins are named Skragget.
in D&D, especially when all of us are chaotic neutral, if you are not able to attend an adventure, expect your character to be controlled by someone else in a fashion where your character is the one who kicks down all the doors, sets off all the traps, and charges blindly at the foes. also expect your character to take the blame for things like when the high level fighter comes along wondering who took the magical sword from his father's crypt.
finally, on a more serious note, there is the game titan (which i am assuming at least one of you has heard of, seeing as it's on the interests list). because the game is so big, takes so long to teach and so much longer to play, i haven't actually been able to convince many of my gaming buddies that it's worth playing. when we do play, however, we always have balanced starting towers after that disaster of a game where our starting towers turned out to be right next to each other.
with the lack of people willing to play Titan being commonplace, i stumbled across a java version of Titan called
Colossus, and it contains numerous variants, a few of which are even worth playing, though the effort to make enough little tiles to play the variant on the board would be too much effort, it is still fun to play.
so that's pretty much all i can think of now. i love gaming, and i think it's great that i found a community where i can post some of my gaming quirks.
