If you call tons of hours of work ( I would estimate that it probably going to be over 100 hours by the time its done) cheap then you really need to sort yourself out. This isn't a conversion of a conventional 24 player map this a huge map and really there was alot missing from the original that has had to be added like more terraforming, builds and interiors. Sorry mate but what you are saying just shows your ignorance of the amount of work this kind of project takes.
if you think 100 hours of work is something special for a 48 players map then you are little weird, cause GOOOD qualified maps take over months kk?, they don't take hours they take days/months.. the owner properly made this map in like months and not hours..
good maps like : sg4, Avaricia, breeze island etc., don't take 100 hours, but more then 1 - 3 months maybe even more..
and here's a example Reforest project's don't take 100 hours, but more then months..
Team Swish rugged lands took 9 months to make, (that a lot and could be made less time) but the quality is good.
Static nightmare: doesn't make his maps in Hours not even days but, MONTHS!!
and a lot of others build team/builders.
They make there map Qualified for mcsg and not Revamping it.
