That’s not new…I’m pretty sure they’ve had that for a while…. I take it we’re talking about http://www.starcave.com/
I don’t see any reason why this site should be 100% flash as other than the flashing buttons in the background and snow like effect everything could be achieved through standard html. If you want those flashy effects you could achieve them through dhtml. Though dhtml isnt exactly great either…
Oddly enough I really like the Sega Racing site even though there really isnt a reason to use flash there either.Its just something about it which looks very clean and easy to use…
