Slavoj Zizek gave a talk at CUNY and Fora has it online, which is pretty handy. It’s a good lecture, if a little long (I suggest skipping to about the 10min mark), that covers quite a bit.
Zizek goes into our relationship with nature, the material and immaterial world, and how it relates to politics and religion. Definitely a good lecture!
It gets me thinking about how do games fit into his understanding of authenticity and what the meaning of games actually is (if anything).
