After much arguing, I finally got the proprieter of my apartment complex to remove IP blocks that have been annoying me for months. Now I have to figure out all of the ports that are most important to me. So im here looking for help. What are all the most useful ports for a PC gamer? (Please specify UDP or TCP.) Some ports in particular I need: half-life, planetside, worms world party, file sharing progs, messenger programs (especially AIM's direct connect function), media viewers, file downloaders/installers (such as auto updaters), and any other common ports you all can think of. Thanks for the help.
