that's one of the things i need to work on. My grand plan when I started the server was to have hunger mod enabled and to have fishing as a class other then cook that can feed people. that got thrown out the window due to negative feed back about hunger mod and that fishermen can't bring in enough fish to feed more then 2 - 3 other people reliably (due to junk and other things you might catch). so as of right now there are only 2 real things a fisherman can catch that people might buy. they are the explosive barrels (only explosives in the game other then respected tools) and and item that allows you to randomly teleport around the map when used ( can teleport you into an inaccessible place and then your stuck).
There are a few HL2 figurines that some people buy when there on the server and a few other thing but the barrels and teleporter are in higher demand. Tomorrow (or later today depending on how you look at it) I'm going to be enabling map rotations, fixing a few minor bugs, i will also look into making it to where fish can heal people when used (like a portable 1 time use med kit), and looking into adding an NPC that will buy fishing items off of people for a certain price. Doing any of this will require some balancing to be done to the fishing class but shouldn't take but a day or two.
There are also a few other things that i will work on for the fishing class ( such as fixing the radios and cores so they can be fished again). while I am on the topic of things ill be doing ill more then likely also put up the stranded server (seeing as I have the files and just need to upload then test them). If anyone has any suggestions on what they would like to see in the fishing class just let me know via steam or the forms.
