I guess reading SF every day for years doesn't help me look past some things.
The gaming company, I'm sure, is VERY casual. That said, I've always been told to wear a suit to an interview...always. I know someone who works there so I plan to do a "fly by" to check things out. I'd feel a little strange not in a suit but times change so I have to keep an open mind.
Sorry OP, didn't mean to thread jack. General consensus is to wear black.
