I would love to see a Fallout game set in the deep South. NOLA and up the Mississippi basin, or better yet, the Everglades. Just consider for a moment a Fallout game set in the Everglades, made by the same guys who went
berserk with Morrowind's flora and fauna.
Make three primary factions: a New Confederacy consisting of vault dwellers obsessed with antebellum Southern lifestyle,
including slavery. Tribals that embrace technology and want to overthrow the New Confederacy and create a socialist government. Lastly, raiders that actually run an underground railroad and attack New Confederate and Tribal settlements to free slaves and steal supplies and were generally libertarian/anarchists (who revered Sherman and Farragut).
The player would be a New Confederate slave who escaped during an attack on a plantation. Since they're not a vault dweller, this allows them to select race (human, mutant, ghoul, or robot, as per Tactics).
Also, since Bethesda's new engine allows for big maps,
give the player a vehicle. Come on, let's get some
Mad max-esque vehicular combat up in this *****! Bonus points if the game's in the Everglades and you get an airboat with a mounted heavy weapon and get to take down giant mutant alligators and pythons.
Bethesda just didn't get the whole message of the Fallout series, it's about rebuilding society and exploring the values of pre-war humanity such as greed and religion. The main plot of New Vegas explores what governments with completely different ideals would be like fighting over a beacon of hope in an otherwise destroyed world. What would Ancient Rome be like if it were around today? What would a city like Vegas be like if people could do whatever they hell they wanted to?
Yes, they did. Very,
very well. FO, FO2, and NV are about the
reconstruction of society; FO3 is about
survival and sacrifice, making it a thematic prequel to the other titles. Unlike the West Coast, the East Coast got
hammered in the Great War; multiple nukes landed on the DC metro area alone. Unlike the West Coast, which by the time of FO1 is already under reconstruction and survival is more or less guaranteed, the Capitol Wasteland is dying and it is up to the player to ensure its survival. And, like the settlements in the Capitol Wasteland, sacrifices have to be made to do that.
