Speaking of D&D, there is of course John Rogers’ 4E comic (Fell’s Five), which is pretty good, much as you’d expect from the creator of Leverage.If you can track them down, the Realm by Arrow Caliber (not to be confused with the comic of same name from Image that's more recent). Very D&D.
Another good fantasy comic with a slightly unusual setting is Kurt Busiek’s Arrowsmith, which is set in a fantasy version of WW1, somewhat similar to Poul Anderson’s Operation Chaos.
