its illegal to charge for anything related on somthing like dbz, if you do, funimation would come crashing around you and sue you until you die. ESF is allowed to relate to the dbz part because they do not gain any profit at all from this work, if they wanted to, they would have to remove all the dbz characters, most of the sounds, and several maps. Because they dont want to do that, also they know that HL is gonna die and they shall not take it any further, there is no point. Anyone making external profit from the mod will cause the mod ot be shut down, somthing so rash causes esf to be very strict about money related things. this should and will answer all of ya questions.. lol
