Joe needs to cut it out with the name calling and insults. He could have handled this much better and professionally. This doesn't reflect well on him in the slightest.
That being said, I am on his side for this one. Dan could have contacted him about this privately without being an instigator on twitter. Instead he decided to make drive-by passive agressive remarks and start the whole shit fest. As an average joe (no pun intended) gamer, things like a .1 difference in score and whether a comment came from a preview or the review don't matter much to me.
When I read a preview or review of the game, I am taking that as a representation of the company/source's attitude on the game. While Dan is technically correct that Joe did represent the wording in the preview as the review, for people that just glance at these things, I do just see a representation of attitude. Quite honestly, if they want me to make a bigger distinction between the two, either dial back the initial hyperbole or give the game a lower score when you have criticisms.
