I think there's plenty of content in there for me to last 6 months if not more for the £11.50 I spent, the only thing I haven't got that I need is the crafting bag. Which I might sub for later. The DLC's like Dark Brotherhood i'll play later, and I'll get the Skyrim content when its cheaper.
If you truly explore every single map, do every quest, listen to all quest lines (they are all but 1 unique), today there is more than 6 months worth of content.
Why I say that. It took me 8 months in 2014 to do the base game (no DLC/expansions then) at 4 hours per day, every day.
Plus quite a few hours with the Khajiit guild at Cyrodiil killing reds and blues.
