I guess I shouldn't be surprised at the ineptitude on display here. It's done by the same developers that served up the bug ridden Blood Bowl game. I remember thinking that was a shame because I desperately wanted to enjoy Blood Bowl... but surely they couldn't ruin another of my favourite franchises? Actually, you'd better believe it, they can and they did. When are publishers going to sit up and take note that Cyanide cannot be relied upon, and surely the only thing keeping them afloat is the strength of the franchise brand they happen to have purchased. Maybe they should get credit for that at least.
Anyway, I've ranted enough about Cyanide, let me tell you that the game, if you can get it to run despite horrible graphics bugs, is shockingly bad. You have a UI that doesn't convey information, units that can't be selected, and it's a great pity because some of the ideas and spy concepts are actually quite neat. Concepts mean squat without a decent implementation though.
Avoid - get your GoT fix through the books or TV series instead.
