It's an adventure game that returns to the first Myst's hub based system, but it uses something similar to Riven's freedom of viewing. Brad Dourif will play the villain and Rand Miller returns to play Atrus. Presto is, of course, very tight-lipped about the plot and the puzzles. It made Grim Fandango that much more special. Maybe Myst III will revive adventure games like Baldur's Gate revived RPGs.

The folks who did the Journeyman Project series have a big budget, a lot of time, and a fairly clever writer. I met her. Her name is Mary. She's a geek like us. She laughs nervously like someone who lives in her head instead of laughing too loud like some guy who works in PR and lives on the retail shelves.
