You can't introduce the add-ons before the core. That'd be like having the Book of Nine Swords without the Player's Handbook. You can introduce them both simultaneously, and I expect that's what will happen.
If the section on combat starts off talking about imagining in my head an attack of swinging a weapon or casting a spell and causing "damage" against some monster... and that's it... fine! Works beautifully. And then if, as I read along, I also come across sidebars that talk about how you could possibly make special attacks as an added part of the fight in addition to that basic attack (like charging, bull rushing, grabbing, knocking prone, aiding another etc.), great! ...
I think that is almost right, but where I side with the thrust of Mattachine's remarks is that I'd say that they
must be developed simultaneously, but can then be introduced together or as core first or as core + some options first. Or at least, there must be enough options developed with the core to make sure that the options work. Otherwise, it will be 2E kits and specialty priests again--all over the place in quality, with frequent, lousy kludges to make up for the fact that concept X wasn't even considered in the "core".
Einstein's dictum: Make things as simple as possible no simpler--seems to be something that D&D design tries to do but gets really free with the "no simpler". "Hey, we've got this mechanic that works just fine, with A, B, C, and D, and covers a lot of cases. But look, if you kind of merge B and C, you can cut out D to just a footnote by these particular parts of A. Then all the players have to do is combine A and the B/C hybrid to get what they want. What could be simpler?"
Would have been a
lot better to kept the clean A, B, C, D version, and had a brief sidebar saying that if you used no options, D is largely irrelevant. In practice, we'll never get that unless there are valid options on the table to keep D in play.
I know both of you already know that, as we've talked about it before. I'm just ranting and clarifying on a pet peeve of mine, for the interest of anyone that hasn't consided what makes options actually work.
