Shivers was one of the better first person adventure games (aka slideshows or "Myst clones"). With other Sierra titles on here getting Shivers 1 and 2 should hopefully be doable.

Those games have challenging puzzles, interesting environments, and fantastic music.

Well, we've gotten these since your post. :)

AND I've purchased them as well :-) Still waiting for Shivers though....

Please allow me to cast another vote for Shivers and for Rama
