I wonder if Mearls here
One of our employees had come up with the initial idea which he used to work up an RPG system for his home group.
was referring to Chris Perkins' AD&D 3rd edition, an amazing take at evolving AD&D.
I was always under the impression that that was a completely different Chris Perkins than the "DM to the Stars". Was I mistaken?
Probably. My guess is that contradictory rules presentation, and different rules in the DMG and PHB, didn't help either!I think this is an area where presentation has a lot to do with it, for good or for ill.
At the least, we can say that 5e has been the least divisive of all WotC editions to-date.
Basically, no matter what your preference for the use of miniatures in D&D, be it theater of the mind, rulers and gridless maps, squares, or even hexes, 5e has something for you.
It's interesting that the 4e DMG presented the 5e system as the default, yet by the time Mearls writes his column that seems to have dropped off the radar - for Mearls, for 4e critics, and presumably for many 4e players
The second big one is that "Common sense" was not clearly presented as an option. The paragraph in the DMG that says you can determine cover based on common sense occurs immediately after a paragraph talking about how the PHB rules should be all DMs need most of the time, and in that context, seems to indicate that "common sense" is equal to "the rule in the PHB." And immediately after the option to use common sense, it goes into an EVEN MORE minis-centric rule that you could use instead of common sense.
I can see viable alternate interpretations, but the one "many 4e players" got seems consistent with the rules as they were written in the books.
I don't think that we saw any 4E groups "ignoring common sense" or the like when it came to cover.
