I certainly hope nobody knows about Planeshift.
The average (or below) online gamer is looking for a game with lots of fighting, action, quests, and options to go nuts with. Being that this game is in pre-alpha, the average online gamer will be dissatisfied, because you can do none of these things. Also, being that the average online gamer is typically impatient and without foresight, they will be angry and contemptuous towards the game because it does not offer these things right now, when they want them.
The average online gamer likes to recommend games to their other online gamer friends. Being that they are thus completely dissatisfied with this game, they will begin spreading bad publicity.
As you can see, the \'average online gamer\' is probably not the type of person the development team wants to be testing their game pre-alpha. The development team probably wants gamers that are helpful, insightful, full of ideas, and know how to properly report bugs. This type of target audience is NOT achieved by mass-promoting. Do we really want another wave of \'this game sucks\' posts flooding the board? We have enough already, in my opinion. I can even give a few examples.
Here,
and here (in regards to the rude people),.
