Research group Forrester believes that the deal, under which Microsoft has paid US$375m for the British games firm, will only have a limited impact on Xbox sales in the short term. The real benefit, Forrester think, will come when Microsoft launches Xbox 2.
"Microsoft is paying a high price for UK games firm Rare, and won't get key titles such as Donkey Kong; the short-term impact on sales of Microsoft's Xbox console will be limited. Unless the move starts a round of acquisitions now (which is possible but not likely), the real impact is likely to come in the next console battle -- Xbox 2 versus Sony's PlayStation 3," wrote Forrester analyst Frederic Diot in a research note published on Tuesday.
Rare has created a number of successful computer games, including Donkey Kong 64, Star Fox and GoldenEye 007.
Nintendo, which previously owned a 49 percent stake in Rare, is retaining the rights to some Rare-affiliated franchises including Donkey Kong and Star Fox. Microsoft has rights to produce sequels to more recent Rare games such as "Banjo-Kazooie," "Conker's Bad Fur Day" and "Perfect Dark."
The price of the Xbox has been cut twice in the UK since the console was launched in March this year, fuelling the belief that it is not performing well against Sony's PS2.
According to Forrester, the purchase of Rare shows how much of its resources Microsoft is willing to dedicate to securing the Xbox's position in the console market.
"Looking at this move alongside the recent Xbox price cut, it seems that short-term console profitability simply isn't a consideration," Diot wrote. "Effectively, the move strengthens the Xbox 2 against the PS3, but at a high price."
In the long term, Diot said, Microsoft needs to create compelling and exclusive games if it is to be a winner in the gaming sector.
