How to create Game Dev Tycoon/Story/Studio 2?

​Hey,

I am a decent programmer and artistic skill is not my strong suit. I have made a few games as a hobby. I have learned Game Development and different programming languages online through Coursera.

I am currently planning to dive into professional game development and I am a big fan of RTS, RPG and simulation games; thus I plan to work in these genres.

The last game I played was Game Dev Tycoon straight for 40 hours+ with only a one hour break for food. I remember looking like a​ ​zombie after that. I am inspired by many Indie Games, but this was my breakthrough. One of my favourite genres and it was simple and complete.

I​ ​have a few queries:

1. From the outside, it looks like a moderate game with 2-3 years of HARD WORK! What are the challenges involved in building a Simulation Game like Game Dev Tycoon? Is it feasible and advisable to create​ your​ first game?

2. Is there a better platform than unity to start with? I am aware of the basics of unity and​ ​have made three tutorial games.

3. Can you give me a complete break up of what I would need to learn/do (Technically) to make a game like game dev tycoon?

4. As I am weak in my artistic skill, I am planning to buy the props and arts from Unity Asset Store etc. Do you think it's the right thing to do? If yes, can you suggest​ some assets to buy or some other online store like Unity asset store?

Thanks! Danish Sinha
