I am for it, for the following reasons.
1. 79% of gamers in Australia have played Minecraft at least once and 22% of those play it everyday of the week!
2. The supportive fan base and very convenient location in the world makes it a big hitter. Also, We have more entertainment venues in Australia than the whole of Oceania and Southern Asia combined!
3. How can you miss it? It is right there! It is cheap and nice, easy to get to from anywhere and have extremely low crime and extremely high gaming population.
Personally, I want the event held at either the Adelaide Showgrounds or the Adelaide Entertainment Centre (the latter if the former is filled up!) This is because Adelaide is the best city in the country and the best city with less than 2 million people in the world!
If you are from another state or city, sorry but it is critically and statistically proven!
