Yukon Valley is a lovely map, but it is starting to show its age. A map based in the interior of Alaska has so much potential, yet this map is a bit disappointing currently. However, with a little bit of love, I think this older map could really become the best map in the game.
First of all, some of the species on the map should be reworked. Moose and Red Fox have gotten good reworks, and Plains Bison have gotten TruRACs, but several other species on this map are far behind in terms of visuals. The main ones that deserve to be revisited (in my opinion) are the Caribou and Grizzly Bear. The Grizzly Bear's models and textures are really outdated and so are the TruRACs for Caribou. There are separate posts that explain how they can be reworked, and I will post the links to them in the thread. I think the Caribou should also have their range reworked so that they can be found in more of the tundra areas of the map.
Second, backfilling! In my opinion the Black Bear and Willow Ptarmigan would be best-suited to be Yukon Valley backfills. Both of these species are abundant in the interior of Alaska and could be common across the forested areas of the map. It would be nice to be able to hunt both Black and Grizzly Bears on the same map, and Willow Ptarmigan would be a great addition in order to add an upland game bird to the map. The Snow Goose, North American Beaver and American Mink would all be great backfilling options as well.
Next, new species! Alaska has a great variety of speciess that could easily be added as huntable animals. These include the Dall Sheep, Wolverine, Spruce Grouse, Snowshoe Hare, Canada Lynx, and Ruffed Grouse. Some of these species could also be added to other maps as well.
Finally, the addition of the Aurora Borealis or Northern Lights at night, because we can already see them on other maps, and it would be awesome to be able to hunt under the Northern Lights on Yukon Valley too. There is already a separate post for this as well.
