I don't know much about virtual engines. I just know that the original games ran fine on these machines, and that these home computers still have dedicated followings, including plenty of old-school RPG fans. I'd imagine they'd be interested in a Gold Box RPG, because frankly, there aren't any MMOs available for their machines, at least none that I'm aware of. I personally started on the Macintosh where I played Pool of Radiance first and there is nothing like that available. Neither on the C64. Not sure about the Atari ST or Amiga, though. The latter has been getting flooded with games lately, which might make it harder to grab the attention of the target audience.

Is this something Claude and other AI tools could potentially help with? For example, building clients for different systems?
