So finally got to play this, thought I'd say my thoughts so far. PC version btw.
In case you have been living under a rock this is a game similar to GTA. Game seems quite fun. I needed to update graphics drivers to stop some problems. The game runs smoothly which is good. I have noticed an issue where if I alt + tab out and then go back in game the frame rate drops massively, making it basically unplayable, so avoid doing that.
The combat seems fun. It's really good, you can choose to snipe the enemies, use the environment to blow them up, run in guns blazing, or use stealth to slip past or knock out enemies. You get a few toys to help with each style too. I killed a few guards in a couple missions and didn't see an alignment drop, refreshing to not have a black and white morality system built into combat. There is an alignment system but it affects other areas.
There is an online, competitive component, but unlike Dark Souls, you can mostly choose whether to participate. Some guy tried invading me but yeah he crashed his bike lol, then I gunned him down as he entered another car.
The hacking system is a major feature of the game. You can find people and gain access to their bank accounts for cash, listen in on their phone conversations, hack security cameras to see many areas, inlcuidng hacking other cameras. There is also lots of things you can blow up, or you can activate traffic lights to cause chaos.
There is very limited crafting to make the aforementioned toys. Also there is a limited skill system. Nothing too complex but it does let you focus your character to your play style.
There are cars of course. They handle like shit though lol. Seems easier to escape cops on foot really.
Overall I am having fun. Game seems large and without morality being forced into combat I feel free to use stealth or combat as I see fit.
Oh and a big hint for if/when you do get invaded/invade others- NPC's don't run and NPC cars don't have screeching wheels when they accelerate.
