Review: YDKJ keeps getting better! - Well... the YDKJ just keeps getting better. Not only have the graphics and sound improved, the online play of this game truly will blow you away. The online play is really easy with great chat options. The game will pair you up instantly with another player and you play a full 15 question game. I recommend this game to anyone who loves crazy trivia games and the YDKJ series. If you only own one trivia game, let this be the one...
Review: YDKJ 5 - I love the game YDKJ but this CD ROM requires a previous version of Windows and it will not work with Windows 7. I have not been able to get it to work on my computer, so I put the CD in a drawer and haven't thought about it since. But in general, the YDKJ games are fun and entertaining.

I love the game YDKJ but this CD ROM requires a previous version of Windows and it will not work with Windows 7. I have not been able to get it to work on my computer, so I put the CD in a drawer and haven't thought about it since. But in general, the YDKJ games are fun and entertaining.

### ⭐⭐⭐⭐⭐ Dementia Fever
*by P***Y on February 23, 2002*

YDKJ Dementia is the best game of all time. Unlike YDKJ mock 2 on playstation, YDKJ has the same Mock 2 questions, but the different things may apply. The Bug Out questions made me better, the gibberish questions made me smarter, and the Anagram question made me blow up. Before each question, any value between $250 and $10,000 is the value of the question, and Schmitty, he's funnier than Cookie. YDKJ Rocks!
