I like dr gunz. They have the most custom gunz server i've played.
They have custom creatures, weapons, items, quests. One of their quest is pacman! Its really pacman!
But there is a lot of lag on most private servers. So i can't play regularly on them. I get pissed when trying to beat people down.
So i just hack ijji gunz. After I get a high enough level that people can't bs me with high level gunz and swords. I would start playing more than hacking.
i created a few custom weapons and clothing. But i didn't know how to texture them so i gave up. I even figured out how to export maya files, import them into blender, export them into .elu gunz files. But i didn't have a server to test them on...
But what eva, i'm getting off topic.
