Minecraft Alpha came out in 2009.
Uhhh dude a while ago
Alpha was an earlier version on minecraft beta, it has poorer graphics, less blocks and far fewer crafting recipes.
Minecraft had a 'soft launch' (started as an alpha/beta) some time around 2006, I believe
Minecraft is no longer in the Alpha stage. It has been updated to Minecraft Beta. Update your Minecraft game client.
You need an a jar from alpha stages, which you can get with Minecraft Nostalgia.
No. The full version of Minecraft will come out after Beta 1.9. Most games have their alpha stages then their beta stages and then the full version comes out.
2009
Minecraft Classic was released May 17th, 2009 The Game was in Alpha and Beta mode until November 18th, 2011
If you buy minecraft, it makes it so your minecraft.net account is registered (so when you log on to the site you can play the alpha version).
