The premise of Alaskan Adventure is simple, you'll travel from region to region of Alaska participating in hunts and various other competitions such as dog sled racing, ice fishing, fly fishing and water fowl shooting.
You are Case Officer Thorn. Your mission: find an assassin who has killed a Russian presidential candidate and is thought to be after the President of the United States next.
As far as racing games go, I'm a pretty traditional sort of fellow. Give me something with lots of speed, or great handling, in a setting that's either realistic or sci-fi, and you've got a happy camper here.
The Expansion Pack's main feature happens to also be its weakest one. I can't imagine any but the most hardcore Trekkies enjoying the pointless, plotless, seemingly endless Virtual Voyager option.
