the thing is we can't discuss about anything if SE doesn't talk about the criteria.
or how many got into alpha.
or how many servers are there for alpha.
or why they don't put another server up for alpha.
too expensive?
well, i paid like 200$ for 1.0 and there got people into alpha who paid not much more than for just the game.

but i heard that's basic business practise, so whatever.
