Every month or so I hold a party with my buddies with gaming as a central highlight. Its a good time, and often lasts 10+ hours.
I supply the food and drinks- no alcohol, only caffine. I have 3 Televisions set up: 2 for gaming only, while another is often used for DVD movies. Also, I have the wiring set up for laptop LAN parties if my pals bring their computers.
Fighting games get the most playtime, but sometimes classics like Smash TV, Warlords, and Guardian Heroes come out. Previously, the entire party has ended up being a nonsop StarCraft tourney.
Each party costs me about $100 (6-10 guests typically) and a lot of setup and cleanup time.
However, its a great time and well worth the effort.
Anyone else have gaming parties?
