The game will focus heavily on choices and your approach to them. Certain choices may lead to fame or infamy and change whole areas. You may be locked out of or gain access to new quests, hidden areas, dialogue etc.
Chapter I - Home
The game's intro which leads to the events which forces the player to leave their home and rally support to reclaim the throne. No combat apart from a battle tutorial. The player is limited to a linear path and limited exploration.
Chapter II - Duty
This part of the game plays like a traditional RPG. You have your retainers (party members,) items and experience to gain to better defeat your enemies. The story will still drive the player through locations but exploration will be free and backtracking to former locations for side-quests is possible. You may need to make promises during quests to receive support for your claim, if you choose not to, any local battles may be more difficult with less men at your disposal. You eventually return to your ancestral home and are crowned.
Chapter III - Reign
Ruling as a monarch, you will have to hold court and hear petitions from the nobles and smallfolk. Any promises you made previously may come back to haunt you as your treasury may not be able to fund the request. Broken promises may lead will lead to infamy and threats upon your life. You command your forces both from the throne and on the field. The chapter ends after winning the events of the invasion.
