I'm kind of wondering what everyone expected him to say.
If he said he hadn't played it Sega would have been pissed, if he said it was awful Sega would have been pissed, if he dodged the question Sega would be pissed and everyone would be pointing it out as proof that Sega knew about the game and Sega would be doubly pissed but because he said it was great (which is what his bosses want him to say) everyone else is pissed.
It's a No Win situation. Apart from the part where Ethan gets to keep his job.
He said exactly what I would expect him to say. Which also happened to kinda blow his credibility.
They aren't mutually exclusive!
