You guys are going to pay a monthly fee for a multiplayer game that isnt even in alpha yet? LLL You do realize Notch still hasnt even finished Minecraft yet? He has also broke numerous promises to his community about features he'd add and saying multiple times things are impossible(Pistons and a few others I cant think of atm) later to be proven wrong by the modding community for him to pay them nothing and put them into the default game.
Minecraft isn't finished? Well it sure plays well enough for me not to care.
Of course I'm not going to pay for this monthly if it becomes a flunk, but the idea appeals widely to an EE/CS major such as me, and I'm sure it appeals to a bunch of others in the same boat. You're saying Notch's past is a reason not to trust him, but I think it is a reason to believe he can get something interesting done. He's got the experience of making multiple games, and he's been able to make Minecraft fun and interesting (who cares if it's "finished" if we have that.)
