1) Vault 15 in Fallout 1
I like this because of first scavenge experience in Fallout. Search in abandoned, destoryed vault, with very own history, but also very same to my own Vault 13. 2 Vaults close together with very different fate, this was the first atmpspehere boost in my Fallout gameplay experience.
I would like to see scavenging in Fonline, very similar to this one, search for lost, destroyed abondoned vault, radioation there, enemy NPC, for pre war stuff and information about the users. We have existing Vault map (base map) who nobody uses, why not to transform it into previous purpose?
2) HUB
Because of music i heard in first few seconds, atmosphere in HUB was very different from others cities locations.. if i breathe deep in HUB, i smell start of post apocalyptic world rebuilding. Dreams of many post apo citizens tread into dust filled with brahmin shits.
It is very sad that HUB is dead city in Fonline. It is because of distance, but also nothing to do there. Enable water merchants, (and supply bases), repetable caravan protecion quests. I can imagine that if there will be repetable caravan protecion quests every half of hour, players will meet there for that purpose => chat, another centre like NCR could be created.
3) Glow
Nuclear bombardment, RADIATION, limited time, forbidden technology, mysterious secrets, jump in the story, quest for Brotherhood of steel membership => for me best moment in Fallout 1/2 game.
I miss radiation element in the game, i miss the limited time you need to finish some quest or you will die because of inner flame, i miss the scavenging, searching for secret technology.
