About two decades ago or so, on the Citizens of the Imperium forum, there was a guy who wasn't satisfied with Traveller. He wanted to be able to take his character's personality, download that personality onto a picotech bot, then have it as part of a neutron star's crystal memory structure as a virtual being, before uploading into an artificially gestated biosculpted human body. Basically, do everything in the last chapters of Alaistair Reynold's Revelation Space novel.
He was stopped short when somebody asked him, "How do you roleplay that?"
I think a similar question kills Eclipse Phase, "How do you actually roleplay this game?"
