I was mainly asking about everyone's DDI access because I wondered how much rules support it would grant me as DM. I'm considering signing up myself. For example, does it support both the original rules and the new Essentials line material? Can they be mixed and matched?
Another related question...how compatible are the two rules sets? If we go with the Essentials materials (which I would support) will it automatically exclude someone like Theroc who is only able to use the older rules?
The
RULES are the same,
essentially (no pun intended). Apart from a few clarifications and updates, the mechanics of D&D 4th ed are little different from what was presented in the Core Rules. The main differences with Essentials are the character classes themselves. You
CAN play Essentials and Core characters together, if you want. As far as I can tell, there's no mechanical reasons you couldn't do it. Now, I can see reasons you wouldn't
want to do it (for example, I'm not sure you'd want both an Essentials Fighter and a Core Fighter in the same game), but that's entirely up to the DM.
Another thing to consider, in terms of what characters you want to allow, if you intend to
ONLY go with Essentials, is that only a few classes and races have been released. Even if you only go with what will be in Essentials (another book is coming out next month), that's still only about half of the classes and races that were ever presented in the Core Rules. So, here are the options as I see them:
1. Everything is fair game, both Core and Essentials. You may want to disallow people playing Essentials and Core versions of the same class in the same group (as above).
2. Only Essentials. That currently limits classes to Fighter (Knight and Slayer), Cleric (Warpriest), Rogue (Thief), and Wizard (Mage) and races to Human, Halfling, Dwarf, Elf, and Eladrin. When Heroes of the Forgotten Kingdoms comes out, we will add, as classes, Druid (Sentinel), Paladin (Cavalier), Ranger (Hunter and Scout), and Warlock (Hexblade) and as races, Dragonborn, Drow, Half-Elf, Half-Orc, and Tiefling. If you allow Dragon magazine materials, the Assassin and Revenant are also added to the above.
2A. Only Essentials, but allow people to play Core versions of classes and races announced but not yet released. This is only an issue for the next month or so. When Heroes of the Forgotten Kingdoms comes out, I believe that is it in terms of class and race release (correct me if I'm wrong here).
3. Essentials and Core that has not been "replaced": The above, plus any other class and race not announced for Essentials. This would allow classes such as Avenger, Barbarian, Bard, Invoker, Psion, and Swordmage and races such as Deva, Gnome, Goliath, and Minotaur. In this scenario, someone who wanted to play a Fighter would need to play a Knight or Slayer from Essentials, but you would also have the options of Ardents, Swordmages, and Wardens available as Core defenders.
