Seems as though Ubisoft are paying the price for some DRM on the UPlay feature in From Dust. Steam are offering full refunds to anyone who's purchased the game through steam.
Ubisoft’s God game From Dust is has been available for less than 24 hours but its purchasers are already being refunded by online distribution giant Steam after a breach of terms by Ubisoft.
The publisher stated that there would be no DRM with the game other than a one-time-activation. However this seems to have turned out to be a big fat lie as the inclusion of metapoint service Uplay demands DRM. Meaning the user would always have to be connected to the internet to log in to Ubisoft’s and play the game
If you purchased the game through Steam, you can request a refund by contacting support here and state your unhappiness with the forced DRM added by Ubisoft. It can take a while for a reply so please be patient.
