Very well said by a well known manager on this forum 

This is actually true which these managers do handle up the community on running whether signature campaign or any tasks been giving out that simply connects out with advertisement or exposure.
This wont really guarantee out success or getting players on playing on the site even if you do put up huge budget on signature campaign.
THere are indeed two type of companies which is those small and big ones and things that it connects on it will really be depending or varying
whether running a campaign would be that sensible or just totally a waste of money and time.
