Return a new brazilian World

They stopped producing country and region specific worlds a long time ago and have no plans to return to them. Wrath worlds have a start time that is more favourable to those in the Americas, but still not good.
A mobile version isn't planned either although I've heard of players using iPads to play.

The only difference I'm aware of is the start time.

A feather.

And what is the difference between tiberium and wrath world?
