It does share some similar mechanics, but I find this game far more suited to western audiences. Fantasy War Tactics is a typical port from Asia, full of bad translation, scantily clad 12-year old girls with giant boobs, huge overworked weapons and armor, etc etc. I would rather play this game with its original art style and similar mechanics.
Hmm, perhaps you're right and this is just a westerned down more child targeted version, since Both games are published by nexon. However, it doesn't just "share" similar mechanics, it's copied FWT right down to the Heroes idle animations. The UI, layout, the heroes, skills, animations, maps, upgrade system, etc etc is 100% FWT reskinned with poly minecrafty design. Even the game files are copys. This kind of stuff still seems weird to me, especially with the crazy high priced IAP in this game, feels a lot like a cash grab rip off.
