Square Enix has announced a rare sale on its mobile titles, along with at least one big release coming soon: Final Fantasy 4, ported to iOS. This version is based on the 3D remake that came out in 2008, so it'll feature active-time battles, full-motion videos and a full orchestral theme. Should be a lot of fun and Square says it's coming soon.
Meanwhile, there's a sale on! Through December 14, Square Enix is offering Final Fantasy 1 and Final Fantasy 2 for US$3.99 each. Final Fantasy 3 is down to $8.99 on the iPhone or $9.99 on the iPad (still not exactly cheap, but definitely well discounted). And the retro style Final Fantasy Dimensions is down to $16.99 for all of the series' episodes.
From December 12 to January 7, Lara Croft and the Guardian of Light will be on sale for 99 cents, and that's a really amazing deal. Square Enix has found a fair bit of success in selling its titles at premium prices, so these don't go on sale too often. Definitely grab them if you're interested while you can.
