Cybersecurity Games that don't TOTALLY suck?

So I'm developing a small training program for 'users' to teach them about Cybersecurity, pretty basic stuff like 'don't write down your password and stick it to the computer'...

I'm wondering what are some fun small like flash style games that are also great tools for Cybersecurity?
If you know of any good games relating to Cybersecurity, feel free to share them, and maybe we can make a little bit of a list.
