epic no, entertaining yes.
And on top of that, human or navi some neat upgradeable weapons and skills.
Then add to that several vehicles, or in the case of the navi, biological vehicles.
Now im certainly not saying this game sits in the big leagues with the plethora of other shooters,but it is in fact quite decent. That being said i certainly don't think this games worth 60 dollars either. For a movie tie in game, its darn good, better than most. The whole game reminds me of playing the multi player maps in GRAW, only fighting man eating plants, feral animals and of course the hostile native inhabitants of pandora, or the soulless capatalistic leathernecks of tera firma. Except you also get to piolet some different craft.
My advice would be rent it for sure, or if ye be lucky and find it on the cheap,
