So, you like Star Trek, eh? Like it so much that you're willing to carry around the gigantic Game Gear, and pay for its constant battery consumption just so that at any point during the day you can whip it out and blow up some Romulans?
I didn't think so. But even with the home adapter, the Advanced Holodeck Tutorial still isn't really worth your time.
The way the game works is straight forward enough; you have Worf, Data, O'Brian, Geordi, and Riker in charge of various systems and information. You select each one, and tell them what to do (where to warp, how fast to warp, raise shields, etc), and try to complete your missions given to you by Captain Picard.
While in a star system, you have to look around manually and try to find your planet or your enemy. This becomes rather frustrating when you're being fired on, and you keep turning and turning trying to find your enemy so that you can fire back, but with no luck, since you have no map or points of reference.
The innovative aspect is that the game seems to randomly generate missions for you, and each time you play your mission will be different. There are a number of star systems, and the computer will pick one, and say that there's an invasion in progress, or that colonists need to be transported up from there, or that you have to move generators from colony A to colony B, where there may or may not be hostile resistance. And I like the game for that reason, but its way too weak of a point to save the game.
If you're a Star Trek fan, and a Game Gear owner, pick the game up, but don't expect too much from it. If you're NOT a Star Trek fan, then there's no reason to even consider it.
