In a summation of the Playstation magazine article on PCgamer.com, this line stood out - 'In Oblivion these [Guilds] provided their own insular quest lines, but in Skyrim they will interact with one another and the main story.'

Would could Guilds 'interacting' with the main story mean? I'm hoping this means they only 'interact' when one has joined a Guild and started the Main Quest. The fact that they 'interact' with eachother does sound great, but I'm slightly dubious on how they might work concerning the main quest (whatever that actually means).
Thoughts?
