3D Quiz DesignHelp

I will try not to make this sound like a "can someone make my complete game for me" type of question. I have been asked by my manager at work to create a concept for a 3d quiz type of "game" in-house training material. We already have the typical powerpoint slide, mulitple choice training system on our intranet but its boring and not well suited for the young coders we have on staff. I am one of the old coders but am game design challenged. I have been looking for inspiration

The training involved in this concept is dead simple but the material is dry. We have some short text for the material then there are 3 questions based on the material. Our current training system can handle this no problem but it isn't interesting. People tend to remember things better if they are engaged.

The first thought I had was a point and click "Adventure game" similar to the adventure game tut.

Yes way overkill but visually interesting. So rather than picking up objects from the different vendors in the small world you would be asked questions.

I am not an artist nor do we have one available on staff so I would be looking for readily available assets too.

So I am looking for ideas from people who have done interesting quiz or training apps.
