Just threw in my couple of bucks. We're long overdue for a good puzzle-adventure.
+Cyan's #Obduction is now nearly 2/3 funded, with 13 days to go! I think it will be alright. This is the Kickstarter from the creators of Myst, Riven and Uru. A totally new world to explore.
If you were holding back on funding due to a lack of details, they have now revealed quite a lot of new concept art and story details in the updates labeled as "Content Update". It's all still just teaser stuff (no real spoilers), but it's sounding very cool.
