All that said- when I use the phrase, "re-inventing the wheel," I want to stress that I don't mean that there is nothing new that comes out. I think it should be obvious that the games of today are different than those of the 70s and 80s and 90s. I try to keep reiterating that vital work gets done from these movements that react to what is around them. But, just like other areas (computer games, for example). It's about how the hobbyist community doesn't recall that these debates already occurred. It's like seeing someone post something on enworld, and not realize that it's been done before. Except ... for fifty years. However, I do agree with you that the debate gets re-contextualized when the debate occurs at different times. It's just that in most fields, the people that are re-contextualizing the debate are aware of the prior debates. I mean ... imagine having a PhD candidate in English say, "Hey, I have a new idea no one has ever had before. Imagine if ... we didn't worry about the author's intention? I know! Totally new, right?" It's not that the debate can't be re-contextualized, so much as it's helpful to know that the debate already occurred.
