It is quite doable. A little JavaScript and a dash of nodejs, some steem to create the tokens and a domain to point to your vps running it all.

Give a reward to your players, X amount of your newest miner when they come out for every Y Steem Power delegated to the bidbot taking in your base token.

Then make sure to come out with a new miner every few weeks and sell it for STEEMP on the market and you have a goldmine. You could even call it goldmine.

This came to me a few weeks ago, but it would take well over a month for me to learn all the coding required and to make it a thing. Someone good with Java could build a MVP within a day.

You could even connect the game to a tribe, and use the tribes currency as the games premium currency. Then take it a step further and burn the premium currency players spend in the game, increasing value for the tribe.
