I was probably too optimistic in the jam, but I really wanted to have BOTH realistic terminals AND fun GUI tools (packet sniffers, network monitors - but more advanced graphical ones that are nicer than the real-world ones we have today ;)).
I feel that when a hacking game is purely in terminal that's cool, BUT ... it gets boring/tiring after a while, and what you want to do as you get further into a game is start to automate more of the drudge work, deploy your own botnets, etc. Scale up, basically.
...but I didn't get that far :D
