Joystiq - Thematic Consistency in RPGs

Joystiq has an editorial about rpgs and thematic consistency.  Rowan Kaiser compares the settings in the old rpgs with those of modern rpgs - from Wizardry to Dragon Age. A quote on how it used to be:

Wizardry's setting was not exceptional in those days. For example, the Might & Magic series was a pastiche of different fantasy and science fiction tropes, all jammed together without rhyme or reason. It's still around, in the Heroes Of Might & Magic strategy spinoffs, where fairies, bears, and dwarves all live together in the same towns. Even Ultima, in the early stages of the genre, included totally random Star Wars-like space combat sections, mandatory for completing the first two games. Across the Pacific, Japanese games like Final Fantasy included airships and aliens alongside its fantasy tropes. I miss this wildness sometimes. Modern RPGs are built around thematic consistency. They're set in worlds that attempt to make sense. To take Dragon Age: Origins as an example: it has a recognizable, historical political system. The characters generally understand the state of the world, and are motivated to deal with that. These are not bad things. As a critic who deals with narrative, creating worlds without inconsistencies appeals to me. My problem is that this has become the default mode for role-playing games. I like the thematically consistent, intense stories of a Dragon Age, yes, but I also miss the goofy weirdness of a Wizardry.
