As much as some people may be buying a Game Of Thrones game for the same characters we encounter in the TV show, ultimately this should be avoided. To have a game with any level of freedom, the events of a GOT game need to take place in a different time and context to those of the series, which could well be in an alternate time that has been alluded to in novels. A popular suggestion would no doubt include Robert's Rebellion, though this too would put players too directly close to events of the series, as many of the characters existing in that time are the same as those in the current series. A better idea then, would be to set the game in a different time altogether. Perhaps 300 years prior to the events of the series when Aegon the Conqueror first came to Westeros and united the Seven Kingdoms. Perhaps a game featuring Ser Duncan the Tall and his squire Egg, the central characters of George R.R. Martin's prequel short stories that take place roughly one hundred years before the series. Or perhaps in an entirely new time period altogether, along with a different location focus. The majority of events in GOT take place in Westeros, but an entire world exists that remains relatively untouched - the smoking ruin of Valyria, the shadow lands of Asshai, the black forests of Ulthos and Sothorys are all shrouded in mystery. This is such a rich mythology that helping to cast some light on the other parts of Martin's world would only make it more interesting.
When not writing Chris spends more time thinking about playing videogames than actually playing them and can usually be found reorganizing his Blu Ray and book collections. He owns four different editions of A Song of Ice and Fire and no, it isn't overkill. He's left the neon haze of Tokyo and Seoul for the more sedate streets of Bournemouth.
