Whenever you finish Cyber Sleuth please please please send me a message letting me know how you liked it. I've been on the fence with this one for a while!
Haven't yet started Hacker's Memory, so can't comment on that. Actually I did force myself into booting the game up for the first time and played some 20 minutes or so - the opening of it is a lot more exciting than Cyber Sleuth's, but I wasn't really in the mood and that was that, really. Will get to it eventually.
