Well, the GEnie files and AotI are supposed to be from the Second Survey, which wasn't published until 1065, so that leaves a little wiggle room. Do the size/atmosphere/hydrosphere codes at least match? As for the HiPop name-changes, I noticed that too with the Linkworlds: Alef to Aleif, Sent to Sentry. Hunter, MJD, or one of the playtesters care to offer some insight into how/why these decisions were made?
