Just in time for Memorial Day weekend, several iOS developers have put up big sales on popular titles. Among the two dozen or so titles on sale, we'd grab Grand Theft Auto III ($0.99), Infinity Blade II ($2.99), Real Racing HD ($1.99), NBA Jam ($1.99, iPad), FIFA Soccer 12 ($2.99), Mass Effect: Infiltrator ($2.99) and Dead Space ($1.99, iPad). Isn't it crazy to think that just ten years ago, Grand Theft Auto III retailed for $49.99? Well, maybe it's not that surprising, but if you've missed out until now, it's a great time to check out the classic game. If you can't spare a buck, rest assured that Rockstar and Electronic Arts will put their games on sale next holiday weekend too. Head over to 9to5Toys for the full list of apps and games on sale this weekend.
