The War of Eustrath by iQubi is an iPhone/iPad Tactical RPG in the style of Fire Emblem and Final Fantasy Tactics.
I’ve been looking for something to tide me over until FFT gets released on the iPhone in September and this is definitely it. The story, characters and gameplay are extremely compelling and due to the fairly compartmentalized battles, it’s a game you can pick up and play for minutes or hours on end. As many of the reviews mention, the only downside is that some of the translations are pretty terrible — but as someone who watches fansubbed anime all the time, I didn’t really have a problem with it.
Highly recommended.
