The Worms titles were discounted on Steam during the week, but the Nuuvem base prices are somewhat lower than the Steam prices.
I made my first purchase from Nuuvem today (Worms Armageddon, apparently the best Worms game), and managed to navigate their site despite being ignorant of 'Brazil-ugese'. The AU dollar value is about 60% of what the value is in Brazilian 'Real", at least with a gouging-free 28Degrees crad.
