Gameloft has announced second-quarter sales of €25 million ($39.3 million), an 8 per cent rise year-on-year, although the company is keen to stress that's 16 per cent growth on a comparable exchange rate basis.

Mobile games generated 94 per cent of the revenue, with the other 6 per cent coming from the company's DS, Xbox Live Arcade and WiiWare releases.

This takes Gameloft's revenues for the first half of 2008 to €50.3 million, up 10 per cent year-on-year (and 17 per cent on the comparable exchange rate basis).

During the first half of this year, 44 per cent of the publisher's revenues came from Europe - the same proportion as for 1H07 - with 29 per cent coming from North America and 28 per cent from the rest of the world. In 1H07, those proportions were 34 per cent and 22 per cent respectively.

Although on the surface that appears to show Gameloft's first-half North American revenues dropped from €15.6 million to €14.6 million year-on-year, when you factor in the weakening state of the dollar against the euro in the past 12 months, it's actually a rise - $21.6 million to $23 million.

Gameloft says the first-half sales are in line with its expectations, and claims its sales growth rate will accelerate in the next six months thanks to "recent and future releases of games for iPhone, N-Gage and mass-market platforms such as Nintendo Wii and DS".

The publisher also points out that Brain Challenge and TV Show King have been highly popular on Xbox Live Arcade and WiiWare respectively.

However it's unclear how significant leaving pure mobile out of its accelerating growth rate will be in terms of Gameloft's future approach to business.
