If there is a prototype. Besides showing and praying, are there other options?

Answer 1

Depends on what stage you are at.
Provide, in addition to the game itself, all sorts of business plans, development strategies, marketing research.
You can try to soft-launch on some small country and collect statistics from it - it will be more convincing - if there is something to soft-launch.
You can additionally go to conferences like the same devgamma and collect feedback / reviews - it can be useful, incl. and then if you show them to the investor.
It is possible to shine more actively with the project on the same devgamma or other conferences - all sorts of contests, stands, etc.
And most importantly - do not limit yourself to one investor.
