How about "They both suck in their own ways"?
The RPG genre (just like pen-and-paper RPGs) is remarkably hidebound.
I guess it's because anything that breaks the mold gets classified as some kind of "hybrid" game style, so all we're left with is a lovingly crafted pile of D&D-clones and D&D-clone-clones.

Call of Cthulhu, D&D 3.5, D&D4e, Vampire the Masquerade, Serenity (Cortex), GURPS, Minimus.
None of those are the same, all of them function differently. Some of them may share elements, like, oh, dice, maybe? But none of them can be called 'the same' other than the tools and methods of play are the same, and you could label video games the same way as you must, for all 'PS3 games' use the PS3 controller, and must sit near it and a TV. (Well, you don't need to, but it's kinda hard to play the games otherwise

)
And I've seen D&D3.5, Call of Cthulhu and Vampire all represented as Video Games, yes. The reverse is also true, I've seen the world of warcraft pen and paper RPG, I've seen BOTH sides of Shadowrun, I've even seen someone pull of the HL1 story as an RPG setting.
So hidebound? Go find a proper 'gaming' store near you and look through their collections, and their upcoming releases. Talk to the regulars. Then come back and tell me pen and paper RPGs are hidebound.
As for PC/console RPGs, I frankly don't know. As a genre, it doesn't appeal to me, oddly. If I want to play an RPG, I'd rather do it in the company of friends, with someone I know creating the story.
As for the topic:
I'm not entirely certain I'd agree with that. Both western and Japanese games are released by publishers who's concern primarily is the 'safety' of the title, and thus how well it will sell. If it won't sell well, they aren't likely to publish it without a damn good cause, and thus, the majority of game releases are "Game like previous game released, slightly different, but recognizably similar. As was said in Zero Punctuation, "it's one of those games that's usually described by starting with 'Like Grand Theft Auto but...'"
