You are absolutely right, blockchain games are always very popular and their coins are always growing in price.
I know popular blockchain games that already exist, for example
I once participated in a bounty, Korean Game company was, so this coin took off and made X5 in February 2018. I won't say her name, it's not ethical. I hope your project will have a similar result. Waiting for your website and white paper.
X5 - it's not so much, similar games on the blockchain can give X30-X40 at best, if you're lucky.
