The whole thing reminds me of Windows "Mojave". For those of you who don't know, look it up. Microsoft decided to rename Vista into Mojave. They then asked people what they thought of Vista and if they would ever buy it. "No! Never. I've heard horrible things about it. It's a bad system." They then try "Mojave" and say, "I love it! This is everything that I've ever wanted. Cool stuff." There's a good look of shock on their faces when they realize that it's actually Vista.
The same thing happens in my German classes. "Who likes Sauerkraut?" "Yuck!" "Have you ever tried it?" "No." "So how can you say that you don't like it?"
I mentioned 4th to the last group that I was in. It was a bad group. A few of the players just started badmouthing it and making statements that were inaccurate. The DM eventually decide to run a short campaign with the group to see how things would go for it. Mind you, he kept a lot of 3.5 in it. Thankfully, I had left that game and taken a couple of the players who were tired of just how ridiculous that group was. They were initially uncertain, but one of the guys, Sarge, looked at my new group at the end of the first game and said, "Thank you. That was the best game of D&D that I've played in years. The system was a lot of fun." We're definitely loving it. I'm 25. The other 2 guys that I stole from the other group are 39 and somewhere in the 40s. They've been playing all their lives. They love the edition and say that it's a lot like the original in feel.
Was there a schism? Yes. 3.5 came to represent crap to us because of the other group. 4th has come to represent fun.
Sarge has the DMG and Player's Guide. He doesn't want the MM because he knows that he'll want to run a campaign then. I find that to be very tempting.
