By the way, remember when you said I should add links to the Lunacraft wiki linking to Eden and Block Earth and Minecraft Pocket Edition? Thanks for asking. I forgot all about those other games until my nephew showed me Eden. It sort blows Lunacraft away. I don't know about Block Earth or Minecraft Pocket Edition, but Eden World Builder is really good.
I haven't downloaded it because it looks pretty lame, the hi-def textures are the only thing it has going for it. Does Block Earth even have ice slides, and does it let you paint things different colors?
I think the ice slides are a much better way to do transportation than minecarts -- you can't make parkour puzzles with minecarts! The rockets are a neat alternative to TNT, but no bounce blocks, and no real water like you said. I saw birds flying by, but are there any creatures you can do anything with?
So they're planning improvements for Block Earth? If it were up to me, I'd say forget about the hi-def graphics, because it makes it harder to use blocks for a different purpose. In Eden we use ladder blocks for bookshelves, doors, filing cabinets, kitchen cabinets, and so on. But if the textures (skins) are hi-def, you wouldn't be able to do that anymore because everything would look like a ladder, so all of those furnishings would look dumb.
Instead, they should add more block shapes, like a thin column/tree trunk, slabs and narrow walls (like vertical slabs), and of course the wedge shapes we already have in Eden. You should be able to use any skin (texture map bitmap) on any block shape, and (like in Eden) be able to paint any block any color. In other words, three attributes for each block cell position: block type, shape, and color. Eden currently has two attributes, because they treat the wedges as separate block types.
This is RUS, as usual, lazy. IMO, MCPE completely overruns eden in terms of awesomeness. the amount of modding and programming that people can do with it, and the community for it is much larger. the only up that eden beats mcpe in is triangle blocks ^-^
Does MCPE have minecarts? or any way to do a transit system? That's what makes Eden work for me. Maybe that's why you say triangle blocks are the good thing about Eden, but you also need the no-friction quality of ice and I don't think Minecraft has that.
The other thing is you can paint anything any color. My understanding with Minecraft is you can only paint wool (and sheep :-) and if you want to paint anything else you need a mod like this one. But Eden has painting as a built-in feature. There's not much you can do with wool, but in Eden you can make a puzzle by painting everything black, or just use yellow ladder and greed shingles as unique wallpaper.
