I guess, but I will need to add plenty of features on release, so I can get a strong start. Though it is true I don’t need all of that right away.
The harsh reality is that ideas are worth nothing. There are a million ideas out there, but what makes a profitable and successful game is the developers. If you have no development skills and no budget, you will not be able to make your game. Your only option is to learn how to script, build, and model yourself.
Personally I would not invest in your project. I do not see in you the willingness to do the dirty work and actually release a fleshed out game.
There is a reason why there is no game like that on roblox. It has an absolutely massive scope and would require astronomical amounts of time & money to complete.
The concepts do sound very interesting and could lead to fun gameplay, but again, concepts are not a game. I wish you luck on your development journey and highly recommend you become familiar with the roblox engine. Investors will respect you far more if you are a competent developer.
