Too much reading, too much walking, too much talking!
I did not like this game anymore than eating Brussels sprouts but I finished it, every gruesome mouthful.
The story was fragmented and difficult to make sense of. I have no idea what was really happening or why. Puzzles were in some cases obscenely difficult, necessitating a walkthrough for completion. A few physics puzzles thrown in only highlighted the poor game controls. Third-person views were often shifted to first-person without warning.
The only plus were a few interesting environments but not worth enduring the game to see them.
Stay away from this one. Uru: Ages beyond Myst has an expansion pack but I just couldn't put myself through hell again...
