Board to Death TV reviews Munchkin Quest. Michaela gives it 8.5, and Steve 7 out of 10 and they summarize the game thusly.

What's Cool:
Hilarious game cards and board.
One of the few funny games out there.
The board is random every time you play.
Snap in pieces to create the board as you explore it.
Great quality for the price you pay.

What's Not:
Some rules need to be more precise.
The rule book is horrible, lots of questions remain unanswered.
Some card will contradict other and create confusion and arguments among players.
The rule book says to create your own rules when the time comes(?).
Monster mobs can be created and this was fixed by giving a cop-out movement rule to monsters.

Neutral Information:
4 Players without expansion.
Long player turns.
