Creating a 4e clone without infringing copyright would be tricky, though. I think WoTC deliberately made this hard to do, by eg renaming monsters and (. . .)
I'm more interested in a thread 'What if the OGL was somehow revoked'.

**As it is, the guys who did OSRIC did a very good job avoiding any possibility of a (c)-claim; some of the other existing retro-clones look a bit shakier, though.
I teach copyright law for a living and I could probably do it correctly, were I willing & able to put in the large amount of effort it would require. I think for most people it would be pretty risky, though.
Just curious: Do you mind sharing your opinion on which clones are on shakier ground?
