I appreciate how they wanted to take the core greatness of Human Revolution and expand on it, but I'm really worried that they've taken it too far. I'm about 5 hours in and have not moved the main story forward beyond reaching the first hub world. It's been Deus Ex: Sidequests. In Human Revolution, the sidequests were nice distractions of just the right length with little to no implications in the main story. So far in Mankind Divided, I have a feeling that the sidequests will have ramifications so I don't feel like I can skip them, which is slowing the pace of the game to a dull slog.
As long as I'm complaining, the hacking minigame that was superb in Human Revolution takes one step forward with the addition of new tools and two steps back with 1) a more finicky interface and 2) percentages that need to be re-balanced. If a node I hack has a 30% chance of me getting caught, I should be successfully capture it 70% of the time, but in the time I've played, the complete opposite has been true, to the point where it's bordering on unfair.
There are also a few technical issues that need sorting, but they're nothing game breaking.
Overall first impression: 7/10.
