That would be great if more Australians made it in European leagues, the national team could go further in the World Cup then! First champions of Asia, then the world! I love your optimism.Hyperbolic really, just about any major sporting code showing off their best talent would sell out, given the supply of that level of quality is so low here for many sports.
Would you choose to go and watch AFL - a sport in Victoria that you can watch live 3-4 times over the weekend over 24 weeks, or a one off chance to watch the biggest soccer side in the world?
I love my football (soccer) and ended up watching the Real Madrid match over the footy on Friday as it was unique and more entertaining given the AFLs nonsensical decision to play the worst side in the league on Friday nights 7 times.
If 2 of the biggest NBA/NFL teams came to Victoria, I'd probably watch that live over AFL as well, because you don't get to see those sports played here at that elite level.
As for FIFA 15 and those games, AFL just doesn't translate well to gaming, nor do AFL developers have the budget of a FIFA. FIFA is a simple, fun game, that for many people turns a boring 90min sport into an exciting 10min thrill. FIFA doesn't represent the game of soccer that well outside of the official names and teams, it just captures the fun aspects by generating scoring chances every 30-60 seconds.
As for kids in school yards playing all the time? Again, soccer is simpler and far safer to play with little to no supervision. Get a ball, put some bags down for goal posts and you're sorted. you can play 1v1 up to 11v11, this isn't so easy with footy. I used to always play soccer at school, the only time we'd play footy was king of the pack. But the vast majority of my friends still followed Aussie Rules, it's just a lot easier to organise a soccer match.
Finally, if soccer does continue to rise - you won't be getting the best players hanging around Australia, they will be packing up their stuff and heading to Europe. So the kids here will never be learning from the best, or interacting with them in any meaningful way. Their heroes are Ronaldo's, Messi's etc. people who they'll likely never meet (or even understand). There is no money to be made in the A-league, it's all in Europe and I don't see that changing - ever!
Moving to Europe is a massive deal, a lot of kids may enjoy football, but they all support Man Utd, Chelsea or Arsenal, not Melbourne Heart or Perth Glory. So the prospect of soccer overtaking footy anytime soon seems very low, especially considering anyone with any talent will leave the country.
