I wasn't sure if he was asking for similar games to those and was aware that they were actualy avaliable on App Store,but in the end my answer was probably not useful at all. Sorry
Yes, both Romance of the Three Kingdoms and Nobunaga's Ambition are available on the App Store, but not in my App Store, conscious decision by the developer not to sell. So are there any similar games to those?
Both games available on US store, check on Tecmo Koei Games https://itunes.apple.com/us/artist/tecmo-koei-games-co.-ltd./id335308086, beware these game have high cost but receive many bad rating from user
I am not US App Store... Got enough of dealing with buying DLCs from all the different marketplaces with XBox Live Marketplace...
I say KoDP You have an indepth simulation of a medival fantasy world. Tip: Build a shrine for maran gor, get MOUNTED TRICERATOPS CALVARY!
Unfortunately I can't think of many worthy alternatives to Romance of the 3 Kingdoms but here are some that pale in comparison to the depth there but might have vague similarities: Rebuild - zombie survivor sim that has a focus on land acquisition. Palm Kingdoms 2 - castle building and resource management with turn based combat. Starbase Orion - a space themed 4x game but has an emphasis on "empire" building.
I think you're missing the point of this thread. Romance of The Three Kingdoms is a strategy game based on a period of chinese history, the three kingdoms era.
Original poster here, I just wanted games that played similar to the Koei games, not really enamoured with the period or anything...
