Filling the Gaps: following in the footsteps of the Wildwood and the Angle

[Scenario]

Or is more regions in the game somehow affecting game performance by any chance? So it's not as easy to have a whole bunch of those?

It's more a consideration of disk space. Each new region comes with a new set of dat files. When we launch an update that includes a new region (such as Tales of Yore/Azanulbizar), we are usually monitoring things closely to make sure that the download weight isn't too onerous on the players (and on our data providers).
