I think it's a really good sign that the things the previewers liked most about the game were the setting, the story, and the characters.
It very much makes me think of Deus Ex (which some of the reviewers explicitly mention - the game feels like Deus Ex).
The combat in Deus Ex to me wasn't stellar, I wouldn't rank it extremely high, but it wasn't bad by any measure. I still enjoyed it, whether I was stealthing my way past enemies I didn't feel deserved death, like cops who are just in my way, or killing everyone in sight like the Dvali in MD. The combat was still fun, but the high point for me was the setting, the locations, the story, characters and lore.
