.So, in short:
ED is not for everyone.
ED has a steep learning curve.
ED requires hours of play to get anywhere.
ED has no 'end game'
ED does not hold your hand.
ED requires effort
Therefore ED will not appeal to a fair number of people. Its not a game for all people and that's fine.
Blackmailing FD into giving keys is also silly. They will choose what they want to do, and since its their livelihoods and jobs on the line they are thinking pretty hard about it.
I don't think the OP is blackmailing FD. Because of the very points you highlight, it will be difficult for ED to get an acceptance that it deserves on Steam and that is why it would be a good idea for people who do understand the nature of ED to be given keys so we can write reviews. I think the steam consumer base is very, very different to the target ED market but understand that FD need to get sales - plus think about when we all started all those years ago, we need to bring on the next generation of ED players.
