For me, they do not bring anything but a little fun and...a waste of time. This game is a very cool advertisement and support of Steem. They earn well with it. To enter the game -you will need an account in Steemit, a private posting key (which serves as a password in the game) and $10 in Steem / SBD to purchase a starting pack.

Yeah i made out really well from that game. Especially after the last month card price pump.

I pretty much sold out though.

yes its weird but i want a red on my account back to 2017~ my account is red and i love it llol

What do you mean by 'locked'? I don't quite understand what you're trying to say with that?

Yeah, the different applications built on Steem are definitely an asset to the platform.

Yeah sure, but hype isn't everything. There is definitely a fundamental form of value present with the Steem blockchain.
You'd be surprised at how many projects are being developed on there.

Well, I think Steem lacks popularity because it has seemingly gone downhill ever since Dan Larimer left, Dan is generally extremely good at getting people interested in his projects, just look at EOS.

Mistakes have been made when he left, there wasn't any significant development for quite some time & there definitely has been some mismanagement of fund (look at the 70% lay-off of staff).
Things are getting better though, Steemit Inc. is communicating more, as can be seen here and they've hired some talented people to manage their company.

I suspect that Steem will slowly regain popularity in the future, especially when they launch SMTs. I definitely could be wrong, but it's a project that's very interesting from a technical point of view.
