Party games (non-sports)- why so few on Xbox?  

Having played many PC party game/game show CD-ROMS on my big screen over the past 5 years in my dedicated basement home theater with large groups (12-18 people), I was wondering- where are these games for the Xbox?

I know about Fuzion Frenzy and Trivial Pursuit, but I'm also looking for games like these on the PC:

Outburst
You Don't Know Jack series
Jeopardy (TV show)
Wheel of Fortune
Family Feud
Who Wants to Be a Millionaire?
etc

Some of you may scoff at the simplicity of some of these titles, but played with a large group in a dark theater with real theater seats, everyone feels they are in the Jeoapry/ Wheel of Fortune/ Millionaire Studio. These games might not be fun playing by yourself, but in a group, they are great for several hours during the holidays or before/after a movie party.

Given its antiquity, I'm amazed how Outburst *still* rates highly in big groups.

Even more amazing is the fact that the original YDKJ games, dating all the way back to 1995/1996, remain THE benchmark for game show simulation, with absolutley seamless flow and immersion.

Any recommendations on the Xbox?

Thanks for the input.

I am disappointed how the PC versions of the games I mentioned in the first post have languished without updates for many years. I fear they will become inoperable/ incompatible after an XP service pack or DirectX update in the near future. I will need to keep an earlier OS load just to play these games (not a big deal with Ghost images, etc).

The game show type trivia/ word games are excellent for adults through parents and grandparents, whereas the fighting/melee type party games are targeted for a teen/ young adult demographic.

I guess I should have titled the thread "Trivia/ puzzle games for Xbox?", as I would include Tetris/ Klax / Bomberman type games in the Party category, too.
