If you live in the netherlands it should timewise be pretty good, considering its at 9PM CEST, which is the dutch timezone.
Australia is a bit meh as its like 5 am, which i can understand. However remember that we need feedback about gameplay on a full server, which in general is a lot more difficult at australian time since the ideal time for that is about 5 am for us folk and 11 am for eu folk, which is where the majority of the players come from.
It is however possible to start a singleplayer game, or perhaps tryout skirmish and give some feedback about that.
Its not just a test to give people a sneak preview, we really want to monitor how things go and look into feedback from players, and for that we need some of our guys to be there as well.
