I didnt see the TGA's but when I saw the news of the reveal the next day. Yes i would say that was a perfect first reveal. The box and Hellblade teaser. It certainly got my attentionWhere they showed several games. I mean doesn't seem your record of the event is too crystal, but then you did say you fell asleep.
By your metric, I guess the XSX reveal at the TGA was spectacular. Box shown, 10 min segment, inengine tailer shown, job well done.
