well, iÂ´m in a counterstrike clan. and we do get our server sponsored. if you take it up to a more proffesional level, you can get anything sponsored, but it has to be worth sponsoring. if you can make it into the publicity yeah, sure sponsors can be interested.
but with a game like esf (no offence) it probally aint gonna work.
mostly servers are created by administrators in companyÂ´s or by people knowing them.
