Your topic brought to mind the soda industry and how it illustrates that there is absolutely nothing you can do to prevent people from making cheap knockoffs of your game or anyone else’s:

Welcome to capitalism.
Notice that Dr. Pepper is the clear winner in that war, and they are on top because of execution, and at this point entrenched tastes, despite all the fake contenders they have to deal with.
I am just going to assume here that War of Stars is complete garbage and not worth playing. If people actually pay money for it then it is their own fault when they realize they wasted their money on trash. The developers that properly execute on their game are usually successful despite the headwinds, and as they continue to execute they gain a reputation of excellence. If Bethesda, Blizzard, Valve, or a handful of other companies release a game I know I can throw my money at them and walk away at least content in having experience a decent product.
If you want to compete for the casual market who does not have a sense of brand loyalty at this point, I guess I would say good luck. Even if they play your polished game and enjoy it, whose to say they don’t just follow their whims from one garbage game to another not giving a **** about what you created?
The real problem is how do you get noticed above all the noise and gain those initial sales? Even without the clones you have a ridiculous amount of games being released every day. There was a video game “crash” in the 80’s that saw a lot of game and console makers go out of business, and part of me wonders if we are headed for the same bust. But people don’t have the same limitations coming to market like they used to, which is good and bad.
I think all you can do is out market them. Attack your potential audience from all angles; social, crowdfund, advertising, forums, etc, etc.
