Name list replacement mods?

I would have to say the ease with which the lists can be worked with is a player-specific thing. You might try a premade list to begin with on a test game off to the side, then maybe try editing it to see how easy/difficult you find it to work with before creating one of your own. I don't use custom name files myself but I just opened a couple of them to remind me of how they are set up and it all looks pretty straightforward to me.

If you have never used S3PE or Packer as package file editors before, that part can be a little daunting at first but we would be happy to help you with that on the NRaas forum boards. :)
