This can't just be me, right? Like I know Skyrim was originally gonna be a GoT game of some sort but just looking at how gorgeous modern games are rn, who else would love a game like this?

Personally for me my wish would be to first, choose your starting area. One of the Kingdoms of Westeros, or one of the free cities of Essos.

After that you then choose your background. Are you a sell sword, a hedge knight, a child of a noble house? Which house are you from and who do you serve? How long have you been around? Etc

Once you have all that figured out and a general character creation is finished you get plopped in at the start of the game. Let's say it's the start of the plot of GoT. From there it's an open world game with an honor system. You can choose to act with compassion, deeds spread through the world of your kind and generous acts! Or you can be a snake playing the game.

There's so much more I have in my head that I could add to this, but is it just me who would like an open world game in that setting where your choices can either have a major or minimal impact based on what you do? (Doesn't have to be set during the events of GoT either. Could be set during, say, the Dance! Or during another famous Targaryen period, or even during the height of the Valyrian Empire!)
