Trivia Game - how to?

concept: Trivia game. Users log into the game. there are chat rooms, each has a topic. for example - a room with 12 users, and the topic is history. questions are asked by a bot. Participants answer in real time. the first person to answer (right) gets points. Scores are recorded and players get prizes accordingly.

Technical requirements for the project:

* Module Development:
o BOT module:
+ a bot per chat-room
+ the bot picks a question based on a category (question from the quiz module)
+ asks the question
+ Timer (for example - 60 seconds per question)
+ declares the winner - gets extra points
+ give the right answer and a link to explanation page (node)

o Timer module ????? We have no idea if such a module exists

o User Statistics - Tracking and Analysis module
+ The Quiz module has some statistics features (develop a new module? customize the Quiz module?)

* Module Customization and Integration
o all of the following need to be integrated with the bot and statistics modules and with each other

o Chat Room
+ http://drupal.org/project/chatroom
+ Limit the number of users per room
+ Display the users' details: name, points..
+ Timer???
+ If all the rooms are full, create a new room for the extra users and populate it with a bot.
+ 1 bot per room - asking the questions
+ first user to answer right - the winner? gets X points

o User Points
+ http://drupal.org/project/userpoints
+ integration with chat room/ bot/ statistics modules
+ Actions to affect the points system:
# correct answer
# wrong answer?
# creating quiestions?
# buy points?? (needs paypal integration)

o Quiz
+ http://drupal.org/project/quiz
+ integration with the rest

o Drawing
+ http://drupal.org/project/drawing
+ integration with the rest

are there any other modules that could help us to achieve this? or do we need to develop new ones? (ones mentioned above)
