Since I'm pretty sure electronic gaming can be covered by everyone else, let us see what board games I have available. I have two sets: ones I own, ones I can likely (maybe) borrow.
There might be more by the time DLCon arrives, if I can convince Ashley to let me spend money. =(
If there is anything in particular you want me to bring, please let me know, because fitting all my shit in the car would be hard. Also, I kinda need to ask to borrow the things I don't own.
OwnArkham Horror (+Dunwich, Innsmouth, Kingsport, Lurker, Curse of the Dark Pharoah, Black Goat, King in Yellow): Ya'll know what this is.
Yggdrasil: We players heroically team up to thwart Ragnorak via desperate card counting, reaching into bags, and swearing.
Flash Point: Fire Rescue: We players heroically team up and die in a fire/collapsing building/explosions. And maybe save a cat.
Shadows Over Camelot (+Merlin): We players heroically reenact Le Morte and save Camelot. Except maybe one of us is a traitor and screws everyone else over and the game devolves into accusations and swearing.
Betrayal at House on the Hill: We players heroically bumble about a haunted house until it turns out one of us is evil. Then the fire bats come.
Space Hulk Deathangel - The Card Game: We players heroically get eaten by genestealers.
Bang (+Dodge City): Sort of like Mafia, except we're all cowboys and we bang a lot.
Blood Bowl Team Manager - The Card Game: We are all managers of fantasy football teams and swear a lot at dice and HOW THE FUCK DID MY MINOTAUR FALL OVER GODDAMMIT ALL.
Cosmic Encounter (+Conflict): Sort of like Diplomacy, except we're all aliens with crazy powers that do ridiculous shit and how did you turn that 4 attack card into 63000 attack, good thing I made my loss into a win, bitch!
Discworld: Ankh-Morpork: A game of hidden roles set in Ankh-Morpork, where you pass the buck of not losing to the guy to the left of the dude about to win because you need to worry about winning, not stopping the other guy from winning!
Dominant Species: Where your ocean spiders that photosynthesize can drop a glacier on the seed eating swamp monkies because that bastard depleted all of the sun from your ocean.
Dungeon Petz: The only game I've played where making sure you clean up the shit cubes is important. Not that it matters, because the monster you're raising is going to die/escape/mutate anyway.
Kill the Overlord: Hot potato where almost everyone will die.
King's Blood: Uno, but significantly funnier.
Lords of Waterdeep: A decent, DnD themed worker placement game. Sorry, no funny description here!
Small World (+Be Not Afraid, +Grand Dames, +Cursed, +Tunnels): Kind of like the Disneyland ride, but with more murder and high fantasy.
Small World: Underground: Same as the above, but underground!
Tanto Cuore (+Expanding the House): Dominion, with more boobs.
We Didn't Playtest This At All: What it says on the tin.
Whack a Catgirl: Goofy little game about hitting con-girls with stuff.
7 Wonders: A draft game where you where curse the bastard to your left for not having wood. SERIOUSLY, WHY DON'T YOU HAVE WOOD? I NEED IT.
Love Letter: Fun little filler game about getting a love letter to a princess.
Game of Thrones (2nd Ed): A distressingly accurate representation of the book/show, filled with treachery, betrayal, sabotage, and slaughter.
Chaos in the Old World (+Horned Rat): We play as the gods of Chaos, competing to see who can fuck up the Warhammer world hardest.
BorrowMansions of Madness (+Forbidden Alchemy): Kinda like Arkham, except one person is the elder gods.
Twilight Imperium 3rd Ed (+Expansions): Goddamn giant space opera epic.
Descent (+Expansions): Kinda like DnD, except competitive.
Cyclades: Conquer Greece through the power of AUCTIONS to curry the favor of the gods.
The Resistance (+Expansion): Mafia, but without elimination.
The Resistance: Avalon: Same as above, but with some new wrinkles.
Twilight Struggle
Shadow Hunters
Taluva
Eclipse
Galaxy Truckers
Tichu
Dominion (+Expansions)
