Well, I'll admit that I didn't read all 5 pages of this topic. I'm feeling a bit lazy, so please forgive me if I post an idea that's similar to somebody else's.
Anyway, I've played Fallout 1, 2 and 3 and there are numerous things I'd love to see further explored in the sequel. Gameplay-wise, I'd like to see a higher rate of getting addicted. Maybe not on the scale as in F1 and 2, but in #3, I find myself popping Ultrajet all the time with no consequences. And even if I do happen to get addicted, all I need to do is visit a doctor or use the "My First Laboratory" household item. How about forcing the player to wait it out or feed the addiction? For RP reasons, it's true that you can avoid erasing your addictions, but it's no fun if you know that the cure is so readily avaible. I'd also like to see 'drunk' effects applied to the game, just for the heck of it. Getting a concussion is better for RP than downing 10 beers. :facepalm:
Storywise, I think it'd be very interesting to witness the Great War firsthand. Maybe it could be a "Tranquility Lane"-type simulation in black and white, placing you in the role of a military-type (General Chase, maybe?), an out-of-luck person who's been rejected from the Vaults, or perhaps even a future Ghoul who survives the impact and radiation of a nearby A-bomb, ? la Carol from Underworld. Imagine what a great moment that'd be: getting knocked to the ground, everything goes white, then you get up and see all the buildings are down, people vaporized, and still more mushroom clouds appearing in the distance. Even if this were a short simulation-type quest, it'd really drive home how devastating the war was. It would be chilling and haunting.
oo: I had always wished that we could've seen such a thing in Fallout 3, but here's hoping for #4. :goodjob:
One other thing I'd like to see is the return of some form of transportation. In Fallout 2, we had the Highwayman which used Small Energy Cells and Microfusion Cells for fuel, so how about a motorcycle for #4? I think it could even work in F3. Perhaps a quest where you need to gather a motorcycle handbrake and gas tank, pieces of scrap metal and other parts, then get the fuel and ride around on it. If there's a concern about exploration being too easy with a vehicle, it could always be restricted by landscapes, roadblocks, or certain enemies (such as Super Mutants and Deathclaws) knocking you off the motorcycle. Haha, how funny that would be. :rofl:
