the inimitable Tim Brannan's post on it with almost every link on the subject so far -- and I must say I find it fascinating.
Just the other day I was telling some officemates about the various D&D editions, while simultaneously explaining to one that Computer RPGs are different from Tabletop RPGs (which used to be the only RPGs), and mentioning rumors that there'd be a 5th Edition.
I'm behind the times, truly. I should really pick up the NY Times more.
Anyway, back to reading retro/neo-clones.
