The new lighting is delicious, probably the best thing added, beds are cool, but weren't really needed. Haven't gotten a chance to play with the redstone repeaters, but I think they would be cool. Anyway, this is success. An a sort of related note, I am now on a mission to count the minecraft clones out there. So far the count is four. I do not plan to link to them because I do not wish to support the popularity of (almost) plagiarism.
