Storyline? No.
Guild quests? Hell yes.
Other good RPGs are Morrowind, Vampire - The Masquerade: Bloodlines, the two Witcher games, and the two Dragon Age games.
Dragon Age: Origins is still £35 for the Ultimate Edition on Xbox. Only around £20 on PC, but not sure if I could run it. I played through a bit of it, but never finished it. Dragon Age 2 was awesome, but I've played as each class at least twice. I could buy the DLC, as I only got the prince one for it, but I think I am done with that game just as I am with Skyrim.
