I just had this really awesome, or perhaps stupid, thought; there is that rumour going around about a Fallout: London, but really wouldn't it be better to do a Fallout: Australia?
And I'm not just saying that because I'm Australia, I'm saying it because think of all the seriously cool mutations they could put into the game!
I mean seriously rabid dogs and scaled up insects with the occasional cool beast like the Deathclaws, the UK would be just more of the same! Not so with Australia, we're already as close to a <a href=http://tvtropes.org/pmwiki/pmwiki.php/Main/DeathWorld>Death World as you're going to get on this planet, now imagine mutated platypuses jumping out of rivers trying to ear your faces, swinging their poisoned paws!
Rabid Kangaroos bounding along, kicking you in the guts (I've seen that happen, it's not fun).
Or how about Kolas scaled up trying to rip your face off (they already do it now, imagine them the size of a grizzly!), it would be like Dropbears brought to life!
So, inspired or stupid? or both!
