Dear,
I have over 15 years of experience in the development of elearning materials, please have a look at my profile to find more details.
For this project, I have an excellent experience on Articulate Storyline and able to do the work for you, but as there is no specific details about the project, this is not a final bid.
Basically, the video input into questions shouldn't need much work, but what other data is used and how many questions, how the data will be provided to me to work on it, so we may need to have a discussion about the project before finalizing the bid.
On the other hand, the form of games, would take a curve in the development as it is depending the structure and complexity, it is a little costly, but of course can be done, again, we need to have a discussion.
Please initiate a discussion with me to give more details and where I could give advice and suggest an offer and bid for you.
Best regards,
