I've had a lot of requests for the GALCIV2 Starwars vs StarTrek Mod since I posted it years ago because all the other download links seem to be broken.
Google drive has changed their access policies so I am going to re-post the link to the mod so that you don't have to request access.
PS: Please note that I didn't create this MOD. All I did was remove ship templates and increase the research costs 50% to make the MOD playable on larger maps. It is my default GalCiv2 MOD of choice to this day.
Note that you do have to research a bit to make this MOD work by increasing the GALCIV2 applications access to memory when loading.
