This is the “central” portion of the Acheton map (click to enlarge):
The most striking difference between Old-IF and New-IF is sheer size. I’ve already gone into the issue with Zork. However, unlike Zork, the size in Acheton doesn’t give me a feel of world-immersion. I’ve been trying to figure out why.
Zork has some random bits like Hades or a robot, but the general intent seems to be a unified dungeon one can lovingly map on a single page. Acheton essentially demands segmentation: there’s an entire hedge maze, an entire ocean, an entire desert, an entire temple, and an entire wizard house complete with two mazes.
Moreover, the setting-as-backstory in Zork, while minimal, goes a long way to providing a unified environment. Flood Control Dam #3 is iconic enough to make a graphical appearance much later. Even the much-reviled Bank of Zork was memorable. I can’t think of any locations in Acheton that move past the merely generic.

I thought I would leave a brief tribute to Adam Atkinson, one of my Phoenix heroes. I only knew Adam through emails over the years but found him a very decent and friendly individual. I had hoped like many that he would beat his illness but sadly it was not to be. The text adventure world is perhaps a strange and parochial one to those not bitten by the bug but Adam was one of its staunchest supporters; he never failed to answer my questions.
RIP.
I’ve seen some lovely tributes to Adam from those in the recreational mathematics community, along with former friends and colleagues. He’s certainly left an impact. (I’ve pasted a collection of links to tributes here https://solutionarchive.com/phpBB3/viewtopic.php?t=1894 )
I usually chatted with Adam on ifMUD. Was also helpful and encouraging on the Phoenix games. First I heard he had an illness.
For those reading this who don’t know, he was instrumental in helping with all the ports to z-code (including at least one that didn’t have a version otherwise)
