I wouldn't mind a Telltale Got/ASOIAF game as long as it's a self contained story. Which is likely what we're getting.
Now my ultimate ASOIAF game would have From Software developing a Demon's/Dark Souls like experience that takes place North of the Wall. After the events of ASOS, the setting strikingly mirrors that of a Souls game in terms of how terrifying and fucked up everything is. You have wights obviously, but then add all kinds of different creatures alive and zombiefied along with White Walkers, and you got yourself a good deal of enemies. You got forests, tombs, underground tunnels built by the children of the forest, icy mountains and snowy wastelands. Add in a lot of crazy NPC Wildlings, friendly wights like Coldhands, skinchangers, greenseers and some CotF and you're good to go.
Maybe have each class you start out with start in different areas with different objectives, like a Night Watchman who survived a wight attack try to find the group he was separated from, or a Red Priest/Priestess coming to the Frozen Shores at the call of R'hllor, a Wildling parent trying to find their child, an assassin sent to scout the lands beyond the wall, etc. Also maybe have White Walkers spawn in an area randomly and give the player a choice of either engaging them, or running away. But let the only way of killing a white walker be the use of obsidian, either daggers or arrows, and have a hard set limited number of them to be found. Ahh man, I'll stop now before I really bum myself out over this never happening.
