I Became a Lord of a Fantasy Game

You died and woke up in a fantasy video game you used to play, but instead of the main character, you take on the role of a useless villain of a city destined to be captured by orcs. Using your knowledge of the game, you set out to protect the city and yourself in a world of monsters and magic.
You have to manage the city that's in a state of mismanagement and corruption. It'll take time and resources, as you upgrade various facilities to boost your city's production. Upgrading your city will not only give you greater income but unlocks new equipment and skills to purchase for battle.
Orcs will attack your city. You must defend against them using your troops. Combat takes form in turn-based card battles in a party of four. Upgrade your deck with various equipment as well as purchasing new cards. Combat requires strategy and thought. A standard JRPG type combat with a twist of having cards drawn each turn instead of traditional fixed skills.
Protecting and managing the city properly will reward you romantically as well. A knightess that's doubtful of your worthiness as her lord, a powerful sorceress and your fiance that's been hurt by your degenerate actions prior to your transmigration into the game, a legendary assassin that's been hired to kill you by corrupt officials in the city, and a princess of a falling kingdom that seeks to claim you for her own.
Will you be able to protect the city and change your fate?
