Metaverse is already out of fashion, so I think we should use the more popular Sylphid 3.
(( Metaverse(OUT) <-------> Neo sylphid 3.0 (IN) ))
And, Sylphid 3.0 version is a version with more minerals, so it will be a map where you can feel the difference with that small difference.
And, you have to change other mappools to other versions as well. The current mappool is almost out of date.
