Traditional mostly.  :)<br/><br/>I do like the psionics system described in Skills and Powers, and the additional specialist wizard options described there too, and the expanded feat options from spells and magic.  :)<br/><br/>I'm a huge fan of forgotten realms, dark sun, spelljammer, and planescape.  I never really learned the last because my GM asked me to learn it through his DMing, and then left for college a year later.
