Im working on raising funding to work on an amazing application. I am in the process of asking people for funding but I need a fair breakdown of the costs. How many hours does it take to develop a video game?
There is no right answer to this question as it is not precise.
Depending on the requirements of your app and your experience/knowledge it can be anything between a few hours and years.
The model design alone can cost you weeks of work. Or imagine an AI - impossible to guess the needed working hours.
