Brilliant choices.

Dust Sweeper is also a really cool steemit project going on, and definetaly worth delegating to.
And obviously Steemmonsters is the BIGGEST Steem related game out there at the moment, and I myself believe that Steemmonsters is the game that will get Steemit in general more known.

I second the @dustsweeper option for delegation if you have the bandwidth. It's a great community oriented project that can delivers a return on the support you give.
