UPDATE: Sanctuary v5 is the latest version. Also in my fileshare is Sanctuary Classic v3, with classic weapon placement and spawning.

Here's my Halo 2 Sanctuary remake, made on the new Forge Island. i tried making the map as close to the Halo 2 Sanctuary as I could, so the map has some unique aesthetic features that I haven't seen on other Sanc remakes. The new natural pieces make the map look more beautiful than the Ravine or the Impact pallet(there's trees in the background!) Because the map is made to replicate the original Sanctuary, I believe no-sprint gametypes would be best for it. It can also support v3 CTF and Slayer very well though.
Here's a video of a walkthrough, and some images from the latest version:
