At least for Nintendo it seems like is relevant enough to show more games or they wouldn't have even a Zelda demo.

As long as you are a playstation gamer or Xbox gamer the show stays very relevant. Last year Sony didn't attend to the gamescom, did that make the gamescom irrelevant?

No disrespect to the OP but E3 is the biggest gaming expo in the world. It's where the biggest announcements happen. Not sure who is questioning E3. Maybe Nintendo fans because of the poor showing last year?

And, what did I say in the OP?

Well the OP is conflicting with what you wrote and what you're questioning. If you meant "is it as relevant as it used to be?" then that's a total different question and one that would fit with what you wrote.

If that is what you meant then no it isn't as relevant as it used to be. There are some events that used to be a joke in comparison that are actually quite big now but E3 still remains the Crown Jewell of all events.

Considering how often I hear E3 is when the industry has the most attention from the public eye in the year, I'd say yes it is. Though, participation is pretty important as well. The more groups present, the better. If a lot of groups are passing on it, it kinda loses some of that spark.

That's it. e3 is the biggest in the world, period. It's still relevant because of that.
