Some of them look real solid i'd go with $PYR. $GALA , $ENJIN and perhaps $DAR and $ENGN off the list both have a really addictive gameplay. DAR consists of mining on a 2D platform if you're more of laid back gamer and $ENGN has a new game around the corner which appears to be like Fortnite on steroids, if you're more into shooters.
Is dar really a legit mining game? That's cool then, I thought mining games are fake. I have tried a few of them before but it looks like you are not really mining but your only being rewarded by cryptos. The other game that you suggested looks pretty sick too. I am a fan of Fortnite and alike games but whats even better is you can now earn cryptos on them. In the op's list I have heard a couple of them.
Enjin was the father of all the gaming tokens although I think axie is more popular on the list but axie is starting to lose its momentum right now. Gala is also a gainer, the coin is showing a good performance last time. I only saw vulcan forge being promoted here before but can't say if its good too or not.
