Does not deserve 5.5!!!
The game plays almost like a single player version of a multiplayer game. You run around a huge map killing every enemy thing you see. I didn't find the missions as repetitive as the official review says. Yes, most of the missions are recycled in different ways but the nature of the game is a shooter. The missions just giving you different reasons to do it.
I think the Na'vi side is a bit more fun because you have close range melee attacks that work well up close. As well as an awesome bow and arrow that can take out most tiny soldiers with one satisfying hit. Plus for some reason, I guess because they are tribal, you get the urge to play with a more hunting style. Climbing to the tops of giant trees and stalking tiny humans and taking them out with your bow and arrow really nails the tribal hunter awesomeness. The RDA side is shooter style only with no melee at all. That can be annoying because when enemies get to close they can be difficult to target because they move so fast when up close. But at least they are huge targets.
The graphics are unbelievable. The Jungles are so detailed and amazing to look at. The best part are the night areas. Everything glows in the dark. The trees, plants, animals. It looks almost like under the ocean. The perspectives are fun too. Playing as the Na'vi everything looks tiny including the humans. When you play as humans everything is huge. It helps to make both sides of the game feel original even though you are actually playing on the same maps.
The movie looks like it'll be awesome, and I think most of the gamers here will become big fans of the sci-fi adventure. It's unfortunate that the official low score review will discourage so many people not to try this game. Hopefully after everyone sees the movie they will be inspired to try this awesome, entertaining game.
And don't always believe the reviews! Most of the time they are right, but not always.
