Yesterday I finished Deus Ex: Mankind Divided, plus the Depserate Measure and Criminal Past DLCs.
Base game I enjoyed. It in no way at all lived up to the scope of the original, but the gameplay was engaging and the augments system made it feel like I was building my own stealth man robot. It could really have done with a bigger world or more fleshed-out locations, and the plot was quite pedestrian when compared to the original.
Depserate Measures was, imho, a travesty of a DLC. Painfully short and it felt like a side mission that was just cut from the original game. It made no sense to play it after finishing the main campaign, and it barely even felt worth bothering with.
Criminal Past, however, I thought was superb. Really a great example of what a good DLC should be. It was a decent length, introduced a fun new area to play around in, it related to the main content but also felt like a fresh story. It was also pleasingly challenging, and stepped up the difficulty from the main campaign.
I'd rate them as 7.5/10 main game; 2/10 Desperate Measures; and 9/10 A Criminal Past.
