What gets me is a rarely (actually don't remember ever) see someone say they hate 4E. They say "I don't like.", they say "I don't like it because of X, Y, and Z", or "Its not for me.", but I don't see anyone say they hate 4E. However I see plenty of people say everyone hates 4E.
Like I have never said I hate 4E, I don't remember ever saying I hate 3E. However I see plenty of people call "naysayers" haters of the given game.
Like for me, when it comes to 3E, if I actually hate it, and own hundreds of books, modules, and PDF's for it, I would hate to see how I would have been if I loved 3E. So I laugh when people accuse me of hating 3E.
As for 4E, I really resent it when people say I don't have enough info to form a valid opinion about 4E. I personally have read many, many, many blogs, press type releases, that 5 page thing released at the D&D experience, etc... So I think my opinion of 4E at thsi pont is very valid.
4E isn't a game I am interested in DMing. I could be talked into playing it if I believe the DM is a good on. There are lots of things I have read that tell me I won't like 4E, from monster write ups to description of playtest fighting, excerpts from those $20.00 Preview books, etc....
I will still buy the "core" rules because there are some ideas I think I will want to steal, but playing it won't be any of my intentions.
Hate has nothing to do with that.
