Details about Minecraft 3DS from the dev stream:
- max world size is 2016x2016, which is not bad...for comparison small worlds on Switch are 900x900ish and largest are 3000x3000ish
- based on Pocket Edition 0.15.4, which launched July 2016, has every feature the game did as of that release
- due to above, no The End yet, but does have the Nether
- redstone contraptions work as expected, they had memory-eating bugs with them at one point but got them all squashed
- they plan on lots of updates over the course of the next 6-8 months, for example targeting 0.16 and adding ocean monuments and associated blocks
- no cross play or world sharing, this is a totally new and different build of the game unique to 3DS
- no multiplayer at launch, they want to put it in eventually (only among 3DSs)
- 3D depth will be added in a patch very, very soon, 99% ready
- mouselook with c-stick including invert Y-axis if you want, other options like view bobbing off, auto-jump
- best unique feature: map is always active on the bottom screen! no need for a map item or dual wielding it or anything
- comes with standard textures, plastic (looks great on 3DS), and city, plus many character skins
