Hollywood Hijinx is long and complex, more so than Zork. You play the nephew of a famous movie producing couple who have died and left you their fortune, on the condition that you are smart enough to find all ten of their movie treasures.
The premise didn't really excite me, but as I read the feelies, I began to be more interested. Also, I had heard many people mention this as a favorite Infocom game. Later, during the game, I began to really get into it, especially with the (Spoiler - click to show)remote controlled model of the Atomic Chihuahua set in Tokyo.
The game is hard. I literally couldn't solve the first problem: getting into the house. I had to look up the invisiclues. The game in general was complex, and I honestly just explored the house once, then relied on the walkthrough to see the rest of the game.
Only a few puzzles seemed really unfair, especially the 'last' big puzzle. But the creativity of this game is outstanding. If I had been looking for a long game to play over a month, this would have been it.
