Superb and amazing game. Very detailed world, good open world game. Has some lacking features compared to WD 2 such as you cannot summon cars, gangsters, you can't have 1 character to have all skills, but more into managing your team with diverse skillsets, with pros and cons, and so on. WD Legion is good on it's own terms. Hacking is simplified. It's not better per se compared to WD 2, but it's a very good game on it's own.
If you love hacking/a bit futuristic gadget, open world city gameplay, stealth like Assassin's Creed series, or go gunblazing action like GTA this is a game for you. Driving is also a bit bad compared to WD2. Movement is okay.
Pros:
+Tons of characters with "unique" story and characters relation with other
+Detailed beautiful city of London
+Gives more challenge because not one character can master it all
+Use your creativity: use your surroundings, your gadget to do it for you, or will you go stealth or gunblazing to finish the mission? You decide!
+Deep, serious and real-world issue quest (minor spoiler i.e human trafficking, organ trafficking, hackers, politic, crowd control methods, etc)
+Lots of clothing/customization
Cons:
-You gotta switch sometimes back and forth because 1 character may not suited to do the job, sometimes kinda annoying
-On high graphics it's kinda heavy and demanding to your machine
-You cannot edit your character's physical appereance (not that you can in WD2)
