I was thinking about mods with a profound impact on the gameplay, like Startreck or Starwars twists, with entirely new races and art.
This is, I don't know if the design document takes into account concurrent mods. I mean, I know it takes into account a sort of player-layer, where, if the base game is modified, the player's mods are not and still modify / disable certain features of the game without being overwritten. But what if the player want to have both the base game available (or a slightly mod-tweaked version) and let's say a Starwars version?
I imagined something like duplicated folders; one would be the official-but-potentially-tweaked version, the others would be "from scratch" remakes, and the lobby would have a "select data folder" thing in its advanced options. This way, someone could have both the base game (tweaked) and "from scratch" remakes available.
Does that sound feasible?
(I'm personally not fond of profound lore-shift with mods, but I don't want to deny them because I'm sure that a big part of the community might be thrilled with that.)
