D&D, like most RPGs, is all about "Let's kill things and take their stuff". ^^

Although I have to say, fiddling with character concepts and trying to find ever new ways of kicking ass is half the fun. And that's kind of what sets D&D 3.X apart from anything else (at least the mainstream stuff) -- there are thousands and thousands of options, classes, feats, spells, you name it. This extreme wealth in character options. And it's really the reason why 3.5, despite all its shortcomings, is still my favourite system.
