How can I create MiniGame In side Game

Hello everyone,

Thank you very much for being so amazing community. I need your help to make this project. here is my situation. I am a conversion student from business to computing at university of greenwich UK. I am doing my MSc project to build a mimigame builder on Unity3D.

1. Model and Behaviour (Script Will be provided)

2. user can create account

3. user can make game

4. user can save and publish their game.

5. other user can play that game.

I was thinking to approach by using inventory system to provide model and behaviour and game state or prefabs to save them and some how publish them. Though at this point I do not have specific Idea How i will solve this.

I am ready to work hard and have 3 months in hand. Please put me in right direction.

Thanks very much for your help and support In advance.
