Excellent- in its day.
It's a giant leap from the cozy Maniac Mansion, and therefore gives you a lot of freedom to move around. The graphics are in the same style as MM, though slightly improved. And there's just something magical about being able to control a tabloid reporter.
Sadly, there's a lot. LucasFilm Games (now LucasArts) tried too hard to make a game that was bigger and bolder than Maniac Mansion, and they mostly failed. It must have been fun and groundbreaking to travel the world in a game, but in this modern age, it's the flaws that are more noticeable. The game just gives you to much of a load, and is too unrewarding for all your work. It's too complicated, and that gets in the way of the fun. It's also a shame that there was never a sequel, since I would have been anxious to see what a new Zak title, made by a more seasoned LucasArts, would be like.
The Bottom Line
This is the game where LucasArts started to get the rhythm of adventuring, realizing that you can't be stuck in a house for a whole game, and you need to move around outside. They were a bit overzealous when they went for the complete opposite, and made this game take place in locations all over the Earth. It's an interesting play, but don't expect to get very much enjoyment out of it, as it's just too overwhelming and confusing. Noteworthy today only historically, as it was the prototype for all LucasAdventures to come.
