Don't you think it is only natural?
Since back then the most common connections to the internet was still on dial-up? So it's only natural for webpages today to scale and actually enhances the user's experience if the technology we have now is used correctly.
But seriously I'm glad that they didn't make this feature a requirement to get the "full story".
But if this new feature is anything like the overlord/shadowbroker(?) DLC where there's a car chase and not another shoot and cover then I think it will be an awesome co-op experience it might even deter people from pirating it.
To be honest when I first read the title "First Person Dungeon Crawlers" I thought about Hexen 2 but as I viewed the video made me realize that I haven't played any games like it and I have been gaming since 90s. I would have been glad to give this a try but the movement and how the game-play just feels weird to me.
