I completed the remake of Riven in two days, in about 11 hours total. I never wanted to stop exploring and discovering what was new and different in this version. The new content is very satisfying, and it all feels like it makes sense in the age of Riven. The new puzzles mixed with the a new "transport system" (trying to avoid spoilers) made me feel like I was playing Riven again for the first time. There are some cool surprises, too. I'm very glad Cyan kept the original score by Robyn Miller, like they did with the Myst remake. The graphics look fantastic as well. Cyan did an amazing job!
