Just got the game today, so here's my review:
Gameplay: Plays like the last season of H2, 2-out of-3 Match with $1,000 per round. With the "Pick-a-Key" Bonus Round worth $20,000 and new wardrobe; losing the bonus round gives you $500 per square (You can still move on to the next game if you win the main game), and the Secret Square worth $1,000 in the 2nd game. Rules-wise like the show itself, so no worries about that.
Materials: No Zingers for the game except for the Center Square which are clips from the show (maybe a good or bad thing as the zingers can be "Hit-or-miss" or Outdated in future play. Questions are regular H2 questions and they are used for the bonus round too. No repeats yet. You start the first "week" with Brad Garrett as the Center Square. 2nd week is Kathy Griffin, 3rd is Jeffery Tambor, which would lead Martin Mull as 4th week. About 1750 questions are used in the game (repeats might be low - including the center square questions)
Graphics: Avatars are the same as the other games. Set- Matches the H2 Set without the host' podium but still good.
Audio: No H2 theme, replaced with a generic soundalike theme. Host Tom Bergeron is the voice of the game: Asking the questions, giving the answers, & explaining the rules. Ding is used for the right answer and buzzer is used for wrong guesses.
Multiplayer: None - You are the X player all the games. Same with Millionaire - They did leave the audio for Multiplayer mode in the folder.
Rating: 3 out of 5 stars - Good Adaptation. Could have been higher with zingers (but remember an certain fan-made version didn't have zingers too) and multiplayer mode.
Anyone else has the game can voice their opinion here as well... I just wanted to get the ball started. Any other questions can also be asked here.
Hope this helps for the game purchase for PC or (future) Wii.
(EDIT: Questions total)
