Two of the games we played over the weekend included:
Timeline: we played this all over the place including breakfast - lots of fun.
Red Dragon Inn: clever little game of adventurers enjoying their drinking.
I think if I was a more dedicated wargamer then there is more enjoyment to be had, but saying that there was some cosplay, miniature painting, CCG tournaments and so much more. I was impressed...
The NASA Deep Space Communications Complex at Canberra I hadn't been to before and it was superb. Not only do we get to see the titanic dishes, but the visitor's centre has experts for us to talk to and displays covering much of NASA's endeavours. There is something cool about seeing a piece of moon rock that was actually brought back by humans.
