Reading through the comments on the L&L page and the thread here, I too was noticing and revelling in the sheer positivity I was seeing. I think WotC might have actually succeeded in doing what they planned to do when they set on on this D&D Next adventure.
So I was inspired by Morrus and decided to create some mockups as well. The fonts on the cover that I could identify with WhatTheFont are: Modesto Condensed for the titles and Modesto Text Medium for the blurb at the bottom of the cover.
I was unable to identify the font used for the D&D logos. My guess is that it's custom, but what do I know? I am not a graphic artist/font expert.
I couldn't decide whether I like "Basic Game" or "Basic Rules" better so I made both. The first set is the artwork (low resolution) from the Mike Mearls column on wizards.com.
Next, we have the artwork associated with D&D Next. That one is nice and High Res.
Finally we have the 3 core book covers all sharing a bit of themselves for the Basic version, so I figured why not all 3 covers sharing the Basic Rules/Game cover?
Let me know what ya think and I hope you enjoy them!
