Lots of conversation about the OSR today.
There are the inevitable discussions about what it is, and what it isn't... and I've never seen debates like this get resolved successfully. Nebulous entities don't work like that, much like the "Powered by the Apocalypse" discussions a few weeks ago.
There have been some very vocal discussions about whether the OSR actually has innovation, or if innovation exists in certain products in spite of the OSR.
There have been a lot of points I agree with, about there being numerous flavours of gaming, and how you are hamstringing yourself if you choose to focus exclusively on recapturing nostalgia.
There have been comments I've laughed at, such as the comment that the OSR is basically the "Scientology of gaming".
I'm sure thee will be more discussion regarding this over the next few days, weeks, months, years... until the next buzzword of gaming comes along, and then everyone can start debating that one.
