[Game of Thrones] How different would things be if Renly and Robb had joined Stannis?
gpt
Stannis would most likely sitt the Iron throne, with Renly and Robb at Storms end and Winterfell as warden of the east and north respectively. There are to many things going on in a song of ice and fire for me to recall all the details that would have changed, but the only thing that made Stannis lose the battle of Blackwater was the surprise attack by Lord Tywin and the remenants of Renlys forces. Robbs initial plan was to keep Tywins forces held up in the riverlands so that Stannis could take Kings landing and cripple the entirety of house Lannister in one blow. That obviously didn't go according to plan due to some mistakes by the Tullys and Tywin was able to beat back the attack on Kings landing. Now imagine if Stannis had been backed up by Renlys army as well (which outnumbered his by quite a bit) and that he was coordinating with Robb to keep Tywin locked up in the riverlands. No amount of wildfire would have been able to stop the one true king then.
