Lazy post this one.
The US D&D OSR has Grognardia.
We have Fighting Fantasist and his companion tumblr blog which serves up images of old 80s White Dwarf/Games Workshop art.
Then of course there’s his classic declaration of what the UK OSR is;
Coopdevil is much more eloquent at rambling on about the history and joys of the UK OSR, and he usually gets there first. Witness his masterful review of all that is good and wonderfull about “What is Dungeons and Dragons?” , a book put out by Penguin/Puffin in the 80s from which I pretty much learnt how to play the game.
So do your self a favour at his blog to yer list 😉
