By the way, at current exchange rates 6 to 10 Euros is about 8 to 14 US Dollars, or 4 to 7 UK Pounds.
Now for a bit of analysis:
This price range is very low compared to the old gen N-Gage. Old gen N-Gage games cost about 40 euros plus taxes when they launched, while the new ones cost 10 euros at most, perhaps as low as 6, and the price goes even lower if you just rent the game for a day or a week. At these prices, no one with a Next Gen N-Gage compatible phone should have any trouble affording the Next Gen games.
Nokia is clearly aiming at making Next Gen N-Gage games impulse purchase items, following in the footsteps of the hugely successful Java phone games industry which uses a similar low price high volume download strategy.
It's also significant that you can try all the games for free, which will presumably mean demo downloads or even time-limited versions of the full games. This should greatly help encourage novices to try phone gaming for the first time, and it will also help existing gamers avoid purchasing low quality games or games that just don't appeal to them.
Another significant thing may be operator billing. Apparently 20 countries around the world will support operator billing on the Next Gen N-Gage at launch, and if these are in the major markets for the platform then it should see an explosion in impulse purchases of games. It takes some effort to get your credit card out and type out the numbers or register it with a purchasing system, whereas games charged to your phone bill will be just a click away. Operator billing could make Next Gen N-Gage games as tempting as the peanuts and drinks in a hotel minibar: always within reach and you don't even have to hand any money over (at least not straight away).
