It's a fair question.   

Both GameCredits and GameUnits are trying to fill the same niche. Making a universal crypto to appeal to gamers and game devs.
Why is PoS better then PoW and why should gamers care?       
   
We're not trying to talk down on your idea, but the comparison is legit, and i'd like to know why I should invest in GameUnits and not in GameCredits
