But episodic console games have had a shaky history too. Look at Shen Mue and El Dorado Gate- episodic adventure/RPG series that suffered due to the demise of the Dreamcast hardware. Or look at Xenosaga. That should've been 6 games, but various constraints only allowed 3.
Basically, episodic console games seem cool, but more often than not, behind the scenes stuff (i.e. development costs, phasing out of old hardware) are a hinderance, while PC's are more modular thus allowing a better platform for episodic content.
We can agree to disagree Haven, but I don't think expansion packs and the whole episodic content is a good thing for console gaming. Cost is prohibitive, you never know the lifespan of the hardware, and console gamers in the US at least want to have the full game all perfect when they plop down the $50 for it; In Japan, yeah, console gamers are more willing to pay for the upgrades and stuff for console games but not US console gamers.
