I'm not a D&D fan but i did sit through a lot of games that my brother and boyfriend were playing, so I do get the vibe.
I looked at the linked article and I prefer the flat version. Too much of the dragon detail gets lost in the chrome variation. I also think the chrome effect is just so a decade ago; isn't web design moving toward flat these days and away from these cheesy Photoshop effects.
I like ampersand very much in the flat version - clever and cool and appropriate. I love ampersands anyway.
The lettering is okay - with so much work on the ampersand it all seems out of scale. I agree with @Mister44 that the arrangement of the old logo would work well with this - I'd even double the size of the ampersand because it's just so great.
