Rule #1: Make the characters likable. If the players don't like them, they won't care. If they don't care, they may quit.
Rule #2: Avoid cliches like you'd avoid an out-of-control ocean liner.
Rule #3: Monty Haul RPGs have a reputation for a reason. REWARD must be matched by RISK.
I agree with many; the story is badly written. There are good spots, but far too many bad ones to gloss over.
Personally, I liked the HoT MAPS. Very different. Mazes on 4 levels. But that's me. YMMV.
