I’m not really into that style of gaming, but I did try “Watch Dogs” for a couple hours. I mention this bc I thought the hacking part was the most interesting, and when I mentioned this to a friend they directed me to picoCTF: https://picoctf.org/. Basically this is a training environment aimed at high schoolers to teach them how to do hacking “capture the flag” competitions. So it’s realistic in terms of teaching real hacking skills, but back when I did it they had a “game mode” where your character walked through this 2D environment and solved challenges as part of a story. I could only solve some of the challenges, but still it was pretty cool. Anyway, the web page is still up, don’t know if they still have the game mode.
