I don't actually play Minecraft and probably never will. I've never played World of Warcraft and never will. I don't believe in phenomenon games and I don't have the time to get addicted to games anymore. But I do develop and clone old games that I used to play and I want to say I know there are some very difficult obstacles to overcome in a game like this but every time I look at a screenshot of Minecraft I always say to myself "are you kidding? that's a funsy project and if that is making money let alone millions(?) then I might have to remake it myself because that is absurd."
So I just wanted to say thank you for making a proper open version and giving Minecraft a run for their money. Also that I hope you make this open source so you can end the cloning madness before it starts.
