There's been almost this 'dilution', where players interested in creating anything beautiful or interesting have been all but drowned out by the colossal group of players, new and old, who have no interest in anything but waiting for the next update and occasionally setting something on fire or cloning something they saw on Yogscast or Sky's LP videos.
The game does not have a goal, I cannot fault people for doing what they enjoy in the slightest, but I do feel that the game has lost its meaning to me over the years. Maybe it's also large changes in my life, like coming out to my parents as transgendered or moving to a new home and struggling to find my place in a hostile world, but overall it's hard for me to feel motivated to play or be involved in the community at anywhere near the level I used to.
Developmentally, the game is still pretty stagnant. May I remind the thread that the Modding API has been promised for two years, but never delivered? I don't know if it's still maintained, but last time I checked a very large mod had been released as almost an 'expansion' for Minecraft called Better than Wolves and was created to vent the frustration of a player who felt that the additions were superficial, unnecessary, and faddish and that they could have been done with much more grace. Personally I prefer Vanilla play, as it's less stressful on both my computer and myself, but I can understand the mindset born of waiting for update after update to a game in (then) perpetual beta, and being consistently disappointed.
Do I dislike Minecraft? Not at all. It's a fun diversion and something that brings my aunt and uncle and cousins and I closer together as a family. There's been so many collaborations and shenanigans and arguments and fistfights and reconciliations over this game between a group of five alone, to say nothing of everyone I've played with, those of them I kept in contact with far past the game, and all the monumental undertakings and petty squabbles of the community as a whole. Because for better or worse, we have become a community. And I'm grateful for that.
And those statistics Alexcamostyle posted were enough, but I had to eviscerate your opinion, sorry.
Forgive me for nitpicking, but this statement bothered me a lot. One of the major divisive forces in our community is the need to silence naysayers. It creates this sort of flock mentality, wherein someone's opinions are a target to be dismantled rather than respected and then artfully debated. I do not agree with OP's opinion, but I do respect his right to hold it, and while I will debate it to the sun goes down, I will not insult him or insinuate that his feelings are something to be picked apart for my own internet glory (back in mah day, we called it e-peen).
