Quake style console on Windows

I am sure many of you remember the legendary Quake series games. We grew up with this stuff. And you remember what was the coolest feature of Quake? No, it was neither the graphics, nor that you could blow your friends in little pieces, after you have killed them: it was the console. It was the only game series that I am aware of (ok, I’m not really a games freak, so don’t take my word for it) that it was offering a ‘console’ to the players.
