TOKYO ( TheStreet) -- In January, James McQuivey of Forrester Research ( FORR) eloquently summarized the 3-D push in one sentence: "If you really want 3-D to work, it's all about the gamers." Two months later, gaming companies are listening.Last week, Nintendo announced plans to release a glasses-free 3-D handheld system, the 3DS, by March 2011. The company's proclamation came just after Sony ( SNE) unveiled its PlayStation 3 motion controller, Move, that would allow gamers to not only play with motion control in HD, but on Sony's 3-D televisions coming in June. All of this 3-D talk comes during a down period for the game industry, which watched February sales dive 15% from the same time last year, according to NPD Group. In 2009, console game sales dropped 8% from 2008, with PC game revenue plummeting 23%. Even if 3-D gaming offers a power-up, the sector may be a few stages away from finding such relief. Despite modest success with 3-D gaming in the PC realm by companies like Nvidia ( NVDA), whose chips and GeForce bundles added depth to games like Ubisoft's Assassin's Creed and Activision's ( ATVI) Call of Duty 4, console makers are just now toying with real 3-D offerings. Firmware and other updates will give the PS3 the ability to play true stereoscopic 3-D games and movies by this summer, with Microsoft ( MSFT) yet to announce 3-D plans for the Xbox 360 and Project Natal motion controller. "These are people who already sit right in front of the TV 7 feet away and stare straight ahead in the dark for hours on end," McQuivey said. "They are the perfect 3-D audience." For those wondering if he's right, here's a look at some five early 3-D offerings that could be a sign of what's to come: James Cameron's Avatar: The Game; publisher: Ubisoft, 20th Century Fox Games, Lightstorm Entertainment; release date: available now. It can only get better from here. Much like its big-screen namesake, Avatar the game looks amazing in 3-D on the PS3 and Xbox (somewhat less so on the non-HD Wii). Much like the movie, though, the aesthetics cover any number of problems. What's the point of making a game version if the game itself isn't very fun to play. The controls are jerky, the story is as weak as Cameron's and the play offers gamers about as many options as the 16-bit 2-D offerings produced nearly 20 years before. It's not the first time a film's video game adaptation has disappointed -- try playing any of the Lord of The Rings games -- but this was a lot of technology and money spent on blue people not doing what you want them to.
