Game Makers Give Away ‘Freemium’ Products - NYTimes.com:
Still paying 99 cents to download a smartphone game? That’s far too much. More developers are now giving their games away — and then charging for extra features.
The strategy is known as freemium, as in free meets premium.
And it is being adopted even by giant game makers like Electronic Arts that might once have sneered at the idea because free games had the reputation of being low quality or full of annoying ads.
