Hello, Sir!

I highly recommend you to take a closer look at point 3.2.
And as for your post, I understand your incomprehension but just let me clarify some details:
1. Soldiers inc. and Soldiers inc: Mobile Warfare are two separate games created by two independent teams of developers. The only thing these games have in common is their setting and in-game lore. And of course, each of these games has its own fans and haters.So many men, so many minds. I personally know a lot of players that play both games and enjoy PC version even more.
2. Time. Soldiers Inc. was released in 2013 while Soldiers Inc: Mobile Warfare was published in 2016. There are three years of difference. It's not a secret for everyone that technologies developed faster and faster nowadays. Just imagine how significantly the game industry may change for 3 years. So it's absolutely normal that the game, launched in 2016 looks much more modern and fresh than its elder brother.
3. Technical complexity. Don't forget that we're talking about technically complicated projects and processes which require much time and effort to be complete. To upgrade the PC game to the mobile version we should completely reconfigure the game balance, graphics, UI/UX design, localization and a lot of other things. Would not it be easier to create a brand new game in this case? Yes, it is. And that is actually what we did, and now you have two fantastic games: Soldiers inc. and Soldiers inc: Mobile Warfare.
Just choose the game you like more or play both of them.
