It's a film tie-in which probably ought to tell you all you need to know about Avatar: The Game. Of course it's not much cop, but if I can't deter you from making the ill-advised purchase, I can at least save you as much money as possible!
Amazon and Play currently have matching prices for the 360, PS3 and Wii versions of the game, which stand head and shoulders above the competition. For the XBox 360 version you stand to make an £8 saving against the next best price from Shop To, the PS3 version will save you just under £3 (next best price is from The Hut) and the Wii version is £5 cheaper than the next cheapest (Shop To again).
What makes Avatar such a great film (to some) is not its derivative story or the quality of the acting but rather the incredible spectacle that it creates—the magic and the fantasy. Unfortunately Avatar: The Game offers none of this. Instead it is a simple, bland and slightly convoluted shooter with nothing special to sell it.
The fact that there are two branching storylines and you can choose your allegiance increases the game's worth and longevity. Sadly however, whichever side you take you'll be treated to an uninspiring quest littered with unmemorable characters and punctuated with action that soon grows tedious. Thankfully Avatar at least looks reasonably pretty with some very nice environments and serviceable, if not great, character models.
Overall, Avatar isn't a terrible game but with so many excellent titles available at the moment, why waste your time and cash on one that is merely mediocre.
