Do some DD and you will immediately see what you said isNOT TRUE!!If there wasnt a market for mobile video games then explain this:
"Sonic At The Olympic Games Tokyo 2020 is an upcoming mobile game that is being published by --------->>>>>>SEGA and will be released onto mobile devices in Spring 2020, and SEGA has just released a few screenshots of the game showcasing what gameplay will look like" https://www.androidheadlines.com/2019/06/games-mobilegames-sega-sonic-tokyoolympics.html
This company is already releasing their console Olympic Games in 2 months...NOV 2019. If they felt there wasnt a market for mobile games then they would just stop there but they are releasing a mobile version a few months later in Spring 2020. That means HPIL and NINTENDO will be the only two companies on the face of the earth releasing a mobile Karate Video Game for the Tokyo 2020 Olympics. KEYWORD :ONLY!!!
As you mentioned, thats "your problem" in which you cant see how big this is.
