You Don't Know Jack is amazing. Funniest trivia franchise ever created.
I played all the PC versions available in Germany years ago with my sister and some friends. We were YDKJ addicts back then (except for this one guy who always chose the wrong anwser - he eventually became the world's greatest YDKJ hater).
Be prepared: The game's host Cookie will make fun of you if you're too slow with the buzzer or choose the wrong answer. Cookie, the crude humor and the brilliant twisted presentation of the questions are the reasons this franchise has still some kind of cult following more than a decade after its initial release.
The new version is available for Wii/PS3/360/PC/DS according to the website, but only for the NA market at the moment, afaik. Localisation of these games must be a nightmare - and Nintendo's complaining about The Last Story.
Get YDKJ guys, you won't regret it.
