In response to post #25834169. You want a completely new map or at least a modded one, then you take up programming/coding and do it yourself. A lot of people don't understand how daunting coding can really be. Some mods are made for years, released, and then improved for the next 5 years and can still have numerous bugs/glitches that sometimes even a team of modders don't understand why it's not working properly. That and the fact that you are talking about, essentially, creating a new map (or modding the original one) takes a lot of room; not a lot of people want to take such a task of extending the map, let-alone the fact that now you have to retexture everything to blend in smoothly, code in hills, NPCs, building, quests, new lore, so on and so forth. You're talking about a crap ton of code. The "Tropical Skyrim" mod (for Skyrim, no duh) alone took at least a year to make (was release a year and a half after skyrim) and that is just a simple layer of code on top of the skyrim map, not actually coding the map to look/behave tropical; I can be standing in the middle of a desert and still get a SNOW storm. Physically extending the map would take YEARS and you're not even guaranteed it will work.
