I vote 3 of them as below (not in particular order):

Game #3: Steem Dominion
It's a pioneer who is trying to communicate with steem blockchain in game, and it's also a game supporting multiple players and let players compete with each other in game at the same time. Though the network is very slow, characters' moving is not smooth in game, many parts need to be polished, but I still recommend this game as I see it's potential.

Game #4: Tap Monster
It's a classic Idle/Incremental/clicking game. The themes/arts of steem monster are handled well in game. The game is complete, and the game-play is smooth.

Game #7: There will be Dragons
A classic arcade game with steem monster themes/arts. The atmosphere is dark enough and the characters are dirty enough. Both of the BGM and sound effect are awesome.
