Meh.. let the close-minded fools come to the wrong conclusions and not buy the game, I certainly won't be holding my breath waiting for them to come back.
I guess since ESO isn't aiming for a niche game it's stupid to go tell someone else to play a different game, but with a completely open game, you'll have just as many people that are super informed to quell most people's concerns with a game when they're brought up - rather than hushing things up, they're basically hiring the players for free to advertize and defend their game.
I think we already do that too much on these forums LOL. Even the slightest bit of information and there's a 7 page thread arguing over it. I honestly don't mind that they've gone completely secretive, I'm just glad they weren't half-hearted about it and let the wrong info out. They would either need a completely open game off the bat or completely secretive, it's foolish to try and do both. Completely open has its flaws for sure, but so does completely secretive. Neither of them are as bad as a secretive game that suddenly opens up completely and shocks unready eyes or a completely open way that decides to shut everyone off all the sudden.
