I don't think MK: DA was a non finished product. For me everything in MK DA works fine. I enjoyed the fighting core of the game. The only real problem I had with the gameplay/fighting is that it was too slow. I am sure the MK team had more stuff planned out for MK: DA such as stage fatalites, but couldn't put them in since limted time at the same time they would rather focus on the gameplay itself. General speaking for myself MK: DA was finished , but certain features were in because of time. Also if you check your history in video games features that didn't make it into a game that the game makers had hoped for , but couldn't do do to time 9 times out of 10 make it into the sequel( MK: Decepetion). I guess my answer to your question is that MK: DA didn't have enought time to input all the "features"aka stage fatalies they had wanted
