For me personally, D:OS might be a sleeper hit. Initially I didn't have nearly the same expectations for it as I had for Project: Eternity and Torment, for example. Now... with P:E they've made some questionable design decisions and the Torment guys still haven't even decided on a combat system IIRC, while D:OS slowly got more and more interesting to me, even though they too have made some decisions I'm not happy about (like getting rid of the fixed male/ female setup, which could have been great, writing wise).
