If you were around the interwebs in 2009, you might remember the emergence of a now well recognized and established Indie Game: Minecraft.
It has spawned, it is believed, a whole new genre of video games: the "builder/adventurer" type game. A wholy modifiable lanscape and an extensive crafting system accompanied by some nice gameplay.
Well, I bring to you Minecraft 3.0: Galaxy 55. While only in Alpha 2, it has the potential to become a nice addition to the genre.
