As I watched Felicia Day interact with a video game version of herself, I was struck by the degree of existential weirdness that was going on in front of me. What must it be like to come face to face with a pre-recorded, interactive version of yourself? I tried to imagine having a branching, BioWare-style conversation with my own video game doppelgänger and couldn’t quite make the leap. Would I be aggressive? Kind? Flirty? Would I push my on-screen likeness around just to see what happened?
