I really like #16 and #17! Definitely a step in the right direction! The only thing that might be a hamper is that the cube part looks a bit like Nintendo GameCube or the Nintendo64 logo. What do you think?

For #17, the way the MeanStudios is all one font size with the different shades of gray is pretty nice, I like that a lot.
Great Work!!
