I’ve been back in Lord of the Rings Online a bunch lately, and as part of my return I went through and made sure all my mods were updated. I’m a bit of a mod and plugin junkie in MMOs whenever I can be. I paid for UOAssist back in the long long ago, I loved tinkering with texture mods for Star Wars and Guild Wars, and I was that weirdo on the forums testing hundreds of World of Warcraft UI mods for my guildies – and that’s just the MMO side!
In fact, there are some mods that I wouldn’t want to play without. I really can’t abide being a group healer in an MMO without an adequate grid-like mod, for example. I don’t want to play SWG Legends without the mod that takes the plasticky NGE interface and turns it back into the classic version. And no matter the game, I really like mods (or API interfaces) that let me see what crap my alts have in their inventories and banks!
What’s your favorite player-made mod for an MMO? Why can’t you live without it, and does its purpose transcend the MMO it was made in?
