Brothers Marek Španěl, and Ondřej Španěl established Bohemia Interactive also some 20 years ago. Operation Flashpoint and then Arma 1,2,3 and few other good games and simulations. There were some serious ups and downs in their career, but they persisted and the rest is history.
The problem and difference is that 20 years. Things were little different then than they are now. Especially for a niche and complex simulators. If you have drive and perhaps some financial support do some more serious market research and then consider if still go for it. High chances really are that the research will tell you: forget it and better quickly swim back to the shore. Its a pity, but its a true and harsh reality of today's life.
Wish you all the luck nonetheless!
