It's essentially a browser based RPG where you have "heroes" that go on quests and fight other heroes in an arena. There are three currencies in the game: Bread, bread crumbs, and gold. Bread is used for recruiting heroes and for skipping to the end of quests if you don't have the time to wait. Gold is used for buying items for your heroes, such as weapons and armours, and also for boosting your heroes' stats and making them stronger and more resilient in fights. You get breadcrumbs every fifteen minutes based on your rank in the game, and you go up in rank by fighting other players and winning their spot. Breadcrumbs can be withdrawn to your Steem Engine wallet and they buy back a portion of it from the Steem Engine market every Sunday.
It's quite addictive, so I figure you should wait until you have less weight on your shoulders before trying it.
If you do decide to give it a go, I would appreciate if you used my referral link. :-)
