Just finished Real Myst, which I borrowed from Gil along with Riven. My desk is full of papers with cryptic pictures, numbers, and notes.
Real Myst is a remake of Myst, redone in real 3D instead of a bunch of Quicktime videos. The graphics are great, my PC at home here could barely handle it. They also added an extra Age at the end that ties Myst and Riven together better.
Yes, I’ll admit to needing to consult a walkthrough a few times, but I got through most of it myself. I’m considering reading the Myst novels if I can find them. Next it’s on to Riven, and then Exile.
