They're both right to a point. The core combat and resolution systems aren't really changing much. The character building aspect of the game is going from about as toolkit-like as you can get with a class and level system to something linear and narrowly defined. Characters from both systems can interact with the game systems successfully, so they are compatible. Characters built in one set, in many cases, can't use the other set's stuff, so it's not compatible.
.....SNIP
I think there are actual issues here, it's not just because we like to rage. Where it turns to rage is where we fail to define what exactly it is we're talking about. Each group might as well turn around and talk to a different brick wall.
Good post, and my post was a bit of self-deprecating humor.
With regards to the first paragraph, and your general perspective I think what we are seeing with "normal" 4E and Essentials are
two avenues or approaches to the same game. In some sense one is "advanced" and requires a build-your-own mentality, whereas the other is "basic" and offers a more linear, we'll-help-you-build-it mentality.
I haven't gone too deeply into Essentials, but I'm wondering if an Essentials fighter, for example, is mainly just a pre-built 4E fighter. They both basically do the same thing, but the standard 4E fighter has more options, more maneuvers (powers) to choose from. An interesting question would be: Could we build or "mimic" an Essentials character with Character Builder and the existing 4E rules?
We must remember that Essentials starts with the Red Box, which is primarily a way to both get new players into the game through an evergreen product that can be sold at Target and other non-gaming, non-bookstores, and it is also the starting point for a way into the very complicated game of Dungeons & Dragons. If you are 12-years old it would be a bit confusing to go from the Red Box to the three core hardcovers, which is why we have
Heroes of the Fallen Lands and the
DM's Kit.
To put it another way, I see Essentials as being Basic D&D to the Advanced core 4E game, yet unlike the relationship of BECMI to AD&D, the two are (almost fully) compatible. You can start with Essentials and move into 4E. An Essentials Slayer and a 4E Fighter may not be able to switch parts around that easily, but both could play in the same game.
With that in mind I think we both need and will get revised core rulebooks. Maybe not in 2011 but certainly by 2012. We certainly don't need revised Power books, or probably even revised PHB 2, but
at least a revised PHB, and probably a revised DMG and MM would be a good thing. Include the errata, expand on and cleanup minor rules, move uncommon and rare magic items back where they belong in the DMG, etc.
