I think there should be new texture packs that cost the same as the hd pack so that Dave can be compensated for making the hd pack free.
There would be different types, such as the:
Moon landing texture pack, that would make dirt look like the surface of the moon and the existing moon look like earth!
Undersea texture pack, which makes it seem like your at the bottom of the ocean!
Different things like this could add a more vibrant Blockheads!
What do you think?
