In case anyone finds interest, a new (large) update for the mod "Goldeneye Source" was just released today. They've been teasing some of the maps and models they clearly worked hard on over the past week leading up to the release, but this post shows a good amount and the quality. Also a download link!
I played with Pistol and her viewers on Twitch several months ago. When she hosted a server. If there is not a player base now, there will be after this update.
Yeah I was playing last night, there were a good amount of people compared to pre-update (40-50 when I was on). They added two new game modes too! (A View to a Kill, and Gun Trade). They really did a good job on the new models & textures though, the only thing that shows it's in "Source" engine is the character animations :P.
