This is just throwing out some ideas for things that will be nearby/available as activities, as well as coordinating games/consoles/etc that will be coming in for the con.
Since most of the con will be taking place at my apartment, we'll have my gaming setup (42" LCD HDTV w/PS3, Wii, PS2 hooked up currently) for console games; we may need an Xbox as well. I also have a second smallish HDTV (24") that I use as a secondary monitor; this can be hooked up to a second console or consoles if we want a second gaming station.
For games of the group variety:
PS3:
Marvel vs. Capcom 3 (Hal)
Wii:
Super Smash Bros Melee (Hal)
Super Smash Bros Brawl (Hal)
Mario Kart: Double Dash (Hal)
Mario Kart: Wii (Hal)
New Super Mario Bros. Wii (Hal)
Other fighting games (Cap'n)
360 (Cap'n)
Fighting games for 360 (Cap'n)
Board/card games:
Arkham Horror (includes Dunwich, Kingsport, and Innsmouth expansions) (Hal)
Betrayal at House on the Hill (Hal)
Gloom (Hal)
Settlers of Catan (Yakumo)
Apples to Apples (Cap'n)
For local activities:
Schlitterbahn (waterpark, for early arrivals)
Gamefellas (local used game store)
Alamo Drafthouse (bistro+movie theater, dunno if there will be any movies worth seeing at DLC6 time though)
Rudy's (technically not an attraction, but everyone in the world seems to want to go so)
Arcade UFOIt'd be nice to get an idea of what - particularly in the way of local activities not at the apartment - people are interested in, since we can possibly get some early planning in for how many cars will be needed for trips and when we can fit stuff in. Also, if you have games to bring, post them and we can get a list of what'll be here and what folks are interested in.
