I don't really know If Tribes fulfill your requirements (I really like LEO and how things play out over there at the moment), but if Tribes isn't on the menu, I have a feeling that anything that has to do with art. And especially "singing", composing music, and such.
Let's make some room to creativity...and talent. We're constantly doing the "steem talking" so how about this for a change?
Can you imagine a world without music...because I can't. So extra help on @dsound maybe? But that's just me...
I'd love to see other suggestions too.
Keep on doing what you've been doing the last few days sis!
Cheers!
