I can only suggest you stepn. The tokenomic was so good. Cryptocitizen is good but it's still under development progress. I just try give you that if sten will give you reliable reward even if you are walking or running. This NFT doesn't relate to the game but you can make your energy worth to be used as it will be giving you a few dollars gradually. In my opinion that if this app is so good as so many people are also using this as well. It has pretty similar scheme like axie infinity but it has a better reward distribution compared with the axie infinity too.
So many people are playing this thing right now.
Cryptocitizen still not launching yet and I think is not effective recommended for OP looking with newly play2earn NFT gaming, I have seen with Cryptocitizen project platform and ever use crybertrade when first time launching with bounty campaign, still don not know why name of project change although I see have potential as bigger NFT at the future. But I don't believe with some project before launching to public and know how interested with investor want to buy and collected cryptocitizen gaming.
