How rpg's should be. Highly recommended.
You have 150 days to find a water chip, and you're only clue leads to *minor spoiler* a dead track. So you're basically on your own having to search, north, south, east and west for the chip, while getting to know the world that surrounds you and choosing to get involved or not with it, and how you do that.
At first I though the 150 days limitation was a bit lame, but since there's more game after this first main quest, and then the timer disappears, it ends up being a cool thing, it adds the time concept to me game, something that lacks in most of them.
It's an amazing gameplay experience that will be different for any player, a clever concept that mixes turn-based action and adventure, all with total freedom.
But hey I don't want to be unfair, so i'll say you can't kill the guy who gives you your main quest...and that's it, that's the only limitation.
You can even choose to side the main bad guys, getting a "bad" ending.
I would say it lacks content, but that's not really true, there's lots of 8 hour games and this one can easily be around 30, is just that I want more, in fact, i'm getting fallout 2 (with the restoration project expansion) while I write this, that's how hooked I am.
But since the formula can and has been improved i give it a 9 instead of a 10.
