Over a week late asking this, but in terms of the Knights of the Old Republic games (the single player RPGs from the early '00s), what's your preference? Currently there are 8 tags nominated under "Star Wars Legends: Knights of the Old Republic (Video Games)" which is the new umbrella tag*, with characters from both games involved, and 2 under "Star Wars Legends: Knights of the Old Republic II", which are both definitely from that game.

*Incidentally, is this one of the places the "odd things" are coming in? AO3's relatively recent reorganisation of the SW tags collapsed the two games into one tag as far as canonicals go, so I can imagine that might have had knock on effects.
