Ravensword: The Falling King [$4.99 / Free] and Mikado Defenders [$2.99 / Free] are two games we really enjoyed. They both now have Lite versions recently released that you should try if you are any kind of RPG or Tower Defense genre fan.
Ravensword: Reviewed in November and given 4 stars - Review
Overall, Ravensword is a great addition to the somewhat scarce landscape of RPG's on the iPhone. It has some flaws, but it's a lot of fun and at the end of the day that's really all that matters. With an estimated 6-8 hours of gameplay, and side quests to keep you busy long after that, I can't help but recommend Ravensword.
And soon we'll also have some exclusive details on the sequel, Ravensword 2, so stay tuned for that.
Mikado Defenders: A Tower Defense that really stood out - Review
The tower defense section of the App Store is arguably just as crowded as the match three and line drawing sections, but Taito has managed to create a really cool looking game with a decent amount of depth to it that should make any fan of the genre happy. It comes with multiple difficulty modes, as well as both a story and endless mode. Impressions in the thread in our forums have been positive so far, and much like Taito's other iPhone games, Mikado Defenders is a lot of fun.
