TwoFaceGames have an established knack for coming up with innovative ways to use the RPG Maker system.  Port Traventor's their biggest game yet, and it's a unique hybrid concept that's first and foremost an idling kingdom manager that also incorporates JRPG-style quests and combat.  It can get a little grindy but in a way that will seem normal to most JRPG fans.  There's no downtime - always something to do and some new upgrade to strive for.  Creative.
