Crowfall is something like RTS meets Minecraft meets EVE Online...if that made any sense? More silly stuff - players will be building personal/guild kingdoms by...playing Tetris!?! Also, before massive battles (hundreds of players), building structures and economy make it into the game, it currently looks rather like MOBA than anything else. Another strange thing is, frequent changes of sex/class/race are likely - account and progression are tied to crow-spirit, not the body. Now, alpha access is expensive but open beta (free tests) is scheduled for this winter, requiring only registration on the site. Here are some early player made videos, starting with some voxel destruction: PS If my incomprehensible intro didn't make any sense, IGN Wiki maybe will.
