Well, not all. I know one that give tokens as a reward for playing, and these tokens will earn holders some dividend. There were no burning or anything, the tokens will still at the exact same value time after time. So?
Then we have to compete with them

A seemingly smart answer, but actually stupid, because it's sort of classic and can only be described as lazy and the exact opposite of thoughtful. Yes, everyone knows you'll compete with them, you have to. If you don't have any plan to compete with them, then why would anyone bother looking at your project?
That's literally the question I asked on the very first place, what set you apart from them? What'll be your competitive advantage? What's your point if differences? Duh.
