You can download the cracked version by typing "minecraftsp mediafire" into google. The first link is a download for MinecraftSP. The only drawback is that you cannot play on most multiplayer servers.
You can go to sites like minecraftforfree. Com to acquire the actual real version of Minecraft. Hope this helps!
I afraid you have no way to play free full version. You have to buy it man.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
