Two posts in one day? Blimey. However I was alerted to the existence of one-year wonder 1990 roller derby show Rollergames by US gameshow fandom legend @lambertman on Twitter, and looking it up on Youtube I love it, and also feel no real need to watch any more than an episode of it.
I only have a basic understanding of what’s going on, you get points for getting high up the banked wall and jumping over the jump and your frontman lapping your opponents (the Wikipedia article is here), basically it’s an excuse for lots of drama and fighting. As such the central conceit doesn’t hold up all that well, but it’s worth watching one episode of for the theatrics.
