Electronic Arts set off an iApp price war last week when it discounted many of its games to just $0.99, sparking the release of Tap Tap Revenge 4 for free and a big games sale from other iOS heavyweight, Namco. All the app makers are engaged in a stiff fight to populate the iTunes App Store top ten lists in time for Christmas — after all, Apple’s lists won’t be updated from December 23, so grabbing a good slot on those lists now is likely to translate into great sales opportunities as all those new iPads hit the store. NB: Notes in retail and shopping news stories from across the planet are confirming what we’ve expected — iPad is this year’s must-have gift in the electronics category. With this in mind, Namco today announced its big game sale, slashing the prices of many of tis titles including its various Pac-Mac games. These reduced prices will be available from tomorrow until January 3, reports claim.
