It's certainly not the best RPG in the App Store (probably not even in the top 10), and It may just be a 75 page book wrapped up in 900 pages of fluff, but as far as mobile RPG's go, it gets the job done.
Queen's Crown is a fun and soundly constructed adventure, even if it does little to push the genre forward. Still, its enjoyable combat and responsive controls make it one of the App Store's better action-RPG picks.
Queen's Crown starts exceedingly well, showing off a brilliant gameplay and a fascinating scenario, but does not fully live up to this great expectations... and overall it's "only" a very good game, but not a masterpiece.
It blindsided me from left field, and I'm still in a daze. And now I am going to make a very bold statement, one that will surely incite controversy: It is my considered opinion that Queen's Crown is the best Korean RPG in the App Store.
