Watched Little Busters and am completley indifferent to it. Going by the reactions it's either the best thing in the world ever or the producers should be shot for releasing such a horrendous crime against humanity. I have gone off this sort of show but am watching because Key.
The update to the Xbox version coming out soon makes it equivalent to the Adventure Update of the PC version. Still has a way to go, but the only big challenge left to implement is The End and the Jungle biome, I think. The enchanting/leveling system too, but I don't believe it'll be that difficult to add that one in.
