Thank you for this information! I would not have known about this if I hadn't checked here. I very much enjoyed Chains of Satinav and have this bookmarked at Steam - looking forward to it-the trailers look really good!
After downloading the game all night long, I've now opened "Memoria" and played for about 10 minutes. Everything installed perfectly and plays very smoothly. I'm so looking forward to playing this over the weekend and beyond. One word of caution: I read a review that said some items might not be available if you use them too soon or out of order, which can cause some frustration. So it might pay to save often. I'm glad that I just happened upon this helpful suggestion.
