Barely a rental...
I bought this game when Amazon had a special price of $18 for this game. I am a big Lost fan and kinda enjoyed the 6 hour experience that was "Via Domus".
I was given advice to NOT buy this game, but lucked out on the price, and decided to go ahead and buy it. When I traded it in, I got the value I paid for it... so I am not too disappointed with the price.
If you are not a Lost person, this is not worthy of your time.

it didn't COMPLETELY suck...
This game does the show no justice at all. Sure, its just as insanely confusing as the show, and the graphics were great (characters looked good, voices matched up well, smoke monster was freaky) but when you weren't solving a "fuse" puzzle or running from the smoke monster, the game was pretty much beat for you- all you had to do was run around and the answers fell into your lap. Oh, and there is NO satisfaction of "Hey I beat a game!" when you win because it ends..well... I guess exactly as I should think it would...CONFUSING.
Don't let me stop you from playing this game, because it was pretty cool for hardcore LOST fans, but...well... Don't buy it full price! I bought it used for $9.99 and you don't know how happy I am for that!

I feel ripped off lol!
I have loved the show Lost since it first aired and was eagerly awaiting playing this game. If youre not a fan of the show, don't bother playing this because you'll just be lost (excuse the pun) as to the storyline. However unlike some other reviewers I found it an enjoyable game to play with the exception of the silly fuse puzzles. Also the "other" off in the distance taking shots at you as you walked through the jungle seemed rather out of the normal storyline. I know gunfire is fairly common in the show but getting fired upon walking to and from the hatch was kind of ridiculous, good thing the guy is a lousy shot.

The mindless collecting of water bottles, coconuts, cans of beer and various other tradable items is mostly a waste of time as you'll only need to trade a few times throughout the game, usually for torches or lanterns so you can see to explore the various dark caves and passageways. Even later in the game after you trade for a gun there are a number of ammo clips you can pick up but you only fire three shots in the entire game. You'll feel pretty foolish picking up all that junk when you finish the game and realize you didn't need most of it.

The graphics are top notch, you'll recognize all your favorite cast member right off and to disagree with previous reviewers I thought the voice impersonations were pretty darn close. The ending was a total surprise, and worth playing just to see that. It's a true to form "Lost" season ending!

That being said as mentioned by other reviewers I feel a little ripped off at paying about 30 bucks for a game that can be finished in 8 or 10 hours, and once finished you'll likely have no desire or motivation to ever play again. If youre looking to add an easy 1000 points to your gamer score this game will do that for you, most all the achievements are fairly simple to get even the hidden ones, however there is one that takes a bit of clever thinking to achieve and another one takes pure blind luck to find. Overall I recommend renting this one for the weekend, once you've played it you'll thank me for that tip.

Great graphics, so-so gameplay
I'm an action/adventure gamer; these are my favorite games. After reading about this game I decided not to buy it, but rather to rent it. It's actually the first game I ever rented. But anyway...I enjoyed it. Sure, I'm a big LOST fan which is probably why I liked it more than other people. The graphics I thought were terrific. Seriously the jungle was crazy detailed and good, and the characters were really good too. Too bad the gameplay wasn't as good as how good the game looks though. You hit invisible boundaries a LOT. All you can do is walk, run a little, and jump much towards the end of the game. The missions are just tricky enough and easy enough. It's a very short game, I probably spend 12 hours or so and I did everything possible believe me. I explored and turned over every leaf, so to speak. It was an easy 1000 achievement points. It could have been a awesome killer game, but it isn't...Still, it's worth playing, especially if you love the TV show. Could have used more characters too, and more difficult missions. But it stuck pretty close to the show, and I liked being my character. I give it 4 out of 5 only because it's so short.

Loser.
Unlike many reviews here, I cannot disparage the lack of gameplay. Our problem was a lack of game! Failed to play properly on three different platforms, none of which is out of date, and none of which has had a hiccup with other more demanding software titles. Real dog of an offering. (We are Lost addicts, and are very disappointed.)
