I guess that's one way of looking at it.
I'll explain my opinion. I feel like Essentials is a 4.5 because they are changing 4.0 to conform to Essentials. I'm not saying that's a bad thing. In fact I like it. But how anyone can say that it's not a new version of the rules when the classes are getting revamped in DDI, and when the monsters have been revamped in Monster Vault, and when even new printed products have the trade dress and conform to the rules mechanics and design philosophy of Essentials is puzzling to me.
They invested these dividends in the on-ramp/basic experience (Essentials) and hopefully will further invest them in exciting new toys. But was that ever the initial intent of 4e?
I would be less happy with a company that isn't willing to change to follow a better trail.
Hey, one of those is my pitch!
It did not get accepted, but I feel like this is a consolation prize.
(Another pitch is similar to an idea that I had, but didn't get into shape for this submission window).
Must have not been something they needed at the time, but it had to be a good pitch for them to make it an example. Which one was it?
