Thanks to Epicrules, I have been taught how to downgrade CK2, which means I've been playing aGoT.
Started as Renly, instantly convinced Stannis to abandon his claim and join me, and marched on King's Landing. Tragically, Loras died during the siege and my army was crushed by the numerically inferior Lannisters. The weakened Lannister army, however, was no match when Stannis landed his 10k+ army in the north and zerg-rushed to King's Landing, taking it in a matter of months, winning the war, and securing me the Iron Throne not a year into the game. I captured and released everyone in the royal family besides Cersei and Joffery, and am now marching north to take out Robb, and shortly after, Mance with the aid of Stannis and the other loyal kingdoms. Now I only need to teach Renly how to operate a vagina in order to produce an heir and I'll be set. So pumped right now.
