List of Regions in Order of Release? (604 views)

Hi,

I bought TLD in late 2014 but I only have about 180 hours in it.
I was watching some older TLD videos by GELtaz and the sort. They often refer to "The New Region" so I was interested in finding out what regions they are reffering to
Could anyone list the regions along with the date they were released?

Please help.

I didn't find the right solution from the Internet.
