I like them when people are allowed to come forward and say why they do or do not like a given edition. I don't like it when people post to a thread thinking they can be insulting and domineering, and tell others they don't know how to play, etc...
I do also dislike people who come here and knock a game they haven't tried playing. I don't care how experienced a gamer you are, reading does not tell you how that games mechanics work together, only playing can.
So that is why I gave 4E two months of play time (over 40 hours). I see how the mechanics work, and have a much better idea of how the classes build. I've been gaming for just about 25 years now, and I didn't "see" all of that just from my reading of it. I had a good sense of it, but that still isn't full understanding.
So I guess add to my list that people should actually spend about 20 plus hours playing and shaking down a new system before talking like they know what they need to know about a game. Bottom line is, unless you have played it, you don't know.
Otherwise, just say, "I read through it, but didn't feel inspired to learn anything more about it." Please don't go on posting like you know how the game will actually play. You don't.
