Check your inbox folks because Nintendo is sending out Super Smash Bros. for Nintendo 3DS demo codes to Club Nintendo members. Yes, even Nintendo Australia!
If you get the email you should get four codes, Nintendo is encouraging you to give them out to friends locally so you can start playing together and practicing. This is the same demo that Japanese folks got earlier in the week.
Update from Nintendo: On 20th September, a demo version of the game will also launch on Nintendo eShop. This demo features the same content and features as the demo that select Club Nintendo members will receive one week earlier, however it can be played a maximum of 30 times.
