Story Engine is a pretty big influence out there in the indie world, sometimes acknowledged, sometimes not. It seems that the publisher, Hubris Games, closed their doors back in 2001, though happily their material is still in stock in some places.
I've always been a bit surprised not to see Aldridge anywhere online, as I'm sure he would get a very hearty warm welcome from the indie folks. Does anyone know what became of him? Is he secretly designing away under a pseudonym? Did he lose his mind to gaming, now scratching his designs into the asylum walls with bloodied fingernails? Or did he just have a kid or something? Inquiring minds want to know.
