Here is "The Commodus Incident" text based point driven story educational fun quiz game: (RC1) http://pixelpretation.com/stuff/severus_rc1.zip
Well, its a damn hard quiz, at least it is meant to be, and don't be alarmed if you can't break the positive score barrier.
I'm aware of the major lack of questions, and I'll be throwing more in constantly. (like 10 a day) Suggest me some cool questions (and answers) and I might just use it!
Technical bit: Unfortunately I didn't get to use Irrlicht here (6 different quizzes rendered on all sides of a cube with timer ticking is overkill)
