Basically, this mod (no, it's not a TC even if he calls it that) is only useful for broadband users with big hard drives. He just took a whole bunch of skins and maps by other people and tossed them into a big pile.
It's not going to become a "standard." Why? Because the majority of people aren't going to go out of their way to spend 5 hours downloading a bunch of stuff, half of which they probably don't want anyway, that they could easily download from this very website. If two people want to play a custom map, they download it. They don't download the huge "Knights of the Force" file pack that has one or two levels that they actually want in it. I wouldn't.
I don't mean to be rude, but that's the truth.
