Grand Kingdom has a traditional RPG design that requires plenty of strategic planning in real time. This game prompts players to participate in turn-based battles that have to be carefully planned. The fantasy setting has a Medieval-inspired theme that includes castles and other romantic landscapes. Mercenaries face each other in epic battles that occur as a result of chaos following the fall of the fictional Oldein Empire. The Four Great Nations have been split and must fight for power and control over precious territory. The ultimate goal for players in the Grand Kingdom is to successfully survive campaigns of warfare across dangerous lands. Over time, small armies grow in strength as they defeat enemies and claim victory with plenty of confidence.
