By D&D typically do you mean just 5e which only added artificers to the list after the 13 PH classes?
4e was full of new classes in supplement after supplement as was 3e. Even the 4e PH added warlord and the 3e PH added sorcerer as new ones for the new editions.
OD&D to AD&D added a ton of...
My experience was different.
I had plenty of fun in core only games but you still had CoDzilla and batman wizards in core once you got past low levels.
I liked a lot of supplements, particularly Unearthed Arcana, to tune the game to taste and enjoyed playing and running high level games with a...
There is also the dual stat adventure Black Monks of Glastonbury which has some 3e mechanics for doing Ars Magica in D&D. I believe the big Ars Magica Order of Hermes edge against other spellcasters, the Parma Magic or Magical Shield magical skill, is done in 3e as a feat which gives spell...
My understanding is that while flexible verb noun casting was the big innovation, it also had levelled spells like D&D (just not vancian slots and spell levels generally going up to 40 or so). So while you had magical skills in Creo (create) and Ignem (fire) and could spontaneously come up with...
My memory is that abilities in Ars Magica are similar to ability modifiers in 3e.
AM Mages are designed to be more powerful than grogs (warriors) or companions which is different from the 3e goal of all classes being balanced against each other. AM balance comes more from the troupe style play...
I don't think that definition of a god quite works.
You can have major gods like the Olympians in Greek Mythology, but then you also have things in Greek Mythology like Nymphs who are minor nature gods and can be a personification of a specific land feature or even a specific tree. There is a...
Things on the sorcerer spell list that stood out to me (Mostly stuff that was previously druid). Looking back I realize a couple were in the 14 sorcerer as well, so this is more a 5e difference than a 24 one.
I played and DMd a bunch of sorcerers in the 3e/Pathfinder 1e era (a lot of NPCs) but...
Anything where magic/psychic abilities are in born and magic users are feared.
Wheel of time comes to mind. There is the Tower which teaches skill but the power is just in certain people and not others to start. The White Cloaks hunt down those with the power.
So some versions of Merlin are he...
The last time I used charm person as a good PC I used it to interrogate bad guys instead of intimidation. I was really sick of threats of torture coming from other (not good) PCs.
I remember using it on a guard and taking him out to lunch/buy drinks at a bar off duty to get him to chat and...
The drawback of temporarily licensed titles.
I always wanted the old DC Magic, Watchmen, and Whos Who sourcebooks.
I would like to get PDFs of old Doctor Who, MERP, The Willow Sourcebook, Thieves World, and others as well.
