I'm going to say that lucky islands is the 3rd most popular game on Cubecraft and since its PvP oriented it really should have a 1.8 mode. Also it would be nice to have a game on the 1.8 server that you can probably find better 1.8 versions for. Skywars is on every server and "defend the block that makes you respawn on floating islands" is also on a ton a servers but lucky islands is pretty unique and I would find it worth playing 1.8 Cubecraft if it was on 1.8 rather than going to any of the other 1/8 networks which I believe have better versions of these games.
