Deus Ex: Mankind Divided could be a very interesting game. Human Revolution was a very solid base from which to build on, and if Eidos Montreal figure out how to make the sufficient improvements, this could be a very good game indeed.
Having said that though, I saw the game at E3 and it didn’t blow me away. From the super exposition heavy opener to the pretty janky looking graphics, there are a few little flags showing up for me. This is early footage though, so at least the latter could be addressed by the time the game ships.
You can now see what I saw too to make up your own mind. Take a look here. Like I said, this needs some work, but the new gadgets and level design are promising. I hope this comes together to be the game I know it can be.
