I think most of us gone into the Conan game because of a general dislike for how D&D, as a fantasy, as gotten (that, and Howard's yarns kicks ass!). How can anyone capture the feel of a Heroic Fantasy when fighters rely so heavily on magical toys, spell casters can blasts hordes with a mighty fireball, and Clerics who just piss out healing!
Mind you, I'm still a fan of 1e AD&D, but at least you can tone down the magic, and alter the game just so slightly to make it feel like S&S. You cant do that with 3e D&D! The rules are meshed into itself, that just removing Alignment throw everything into chaos! One of the thing I dislike about d20 is that it is bulky and restrictive. I like to play with systems that are fairly light. When I play D&D, I use simplified versions of D20 (much like Pathfinder), then I use much of the Conan RPG rules, and I just make up my own worlds (often throwing in a good number of AD&D elements in to the fold). In my games, you can still find Magic Items, but they are not just rare and dangerous, they usually have a wide range of powers (and side-effects), and a mind of their own! Encounters are in keeping with Conan - human encounters are vary common, with the occasional encounter with an otherworldly creature. I also like to look though the old Deities & Demigods (note that I count the Cthulhu, Melniboné, and Hyborian Age mythos as apart of the selection, as they were dropped do to copyrights) book to look for Gods and Demon Lords to full my worlds. When I do use Humanoid races, they are typically rare or unplayable. An Elf for example, play more like a Nymph then a Tolkien Elf, and gains Druid abilities as they advance in what level they are advancing in (they need twice the amount of EXP to gain levels). As for the Conan rules, it has more of what I like in a fantasy. I hate Paladins! D&D Rangers are gay! Temptresses are way better them Brads. Allegiance, Reputation, and Honour is way better then Alignment. I love the Dodge/Parry Defense system (you become to dependent on heavy and magic armor without it). The sorcery is really cool. And most of all, the way the Conan book tells players how they can take all that retarded sh!t Wiz-bros passes off as fantasy, blow it out your ass!
Oh, if you are going to use the Sorcery system, using the
Savant: Variant Scholar class & Sorcery rules is the best way to go!
