I recently started playing dcity (dcity.io) and I have to say it's a very interesting model. Its an NFT game currently on Steem and looking to transition to Hive. As with many Steem-based games, there is a rewards system for the best players. Players can earn both SIM tokens which are native to the game, and Steem if they are high enough in the rankings. I recently bought enough buildings to be able to receive some weekly Steem. I think it's definitely a cool game to check out if you're into that sort of thing! To be honest, who isn't?? Have you played dCity before?
