As someone that loves the modern Fallout games, and even enjoyed the flawed and divisive Fallout 4, I've been thinking for awhile on what I want to see done to significant improve a game that drastically needs it. I'm sure there are a few more Fallout fans out there too and I'm curious to see different viewpoints on this.
- Improved/New Engine - Bethesda isn't exactly known for creating stable and bug free games. As a fan, I can overlook them for the big game experiences they offer, but it's bad, and a lot of what was bad in Fallout 3, is still bad in Fallout 4. Some things got cleaned up, but so much is still super buggy, to the point that it's very clear its a problem with the engine and not just something that can be patched. We've all seen tables with items freakout, or ragdolls go nuts, or all manner of different visual issues that have been around since Fallout 3. I think they need to vastly overhaul things as they've stretched this engine as far as it can go.
- Improved UI - I dealt with the Pipboy UI for two games and while it was never great, it was functional. With Fallout 4, I was hoping for an overhaul or something, because its frustrating to use when you have a lot of crap. Of course, Fallout 4 came out and it's the same thing. I'm not sure if they are too stubborn to move away from the Pipboy or are worried that updating it to be smooth and nice in design would take away from the aesthetic, but it's so frustrating to use now. Even mods really don't do anything to improve it other than with better organization. Some people might want the dialogue improved, or better gameplay or whatever, I just want to be able to browse my Pipboy better!
- New Country - I know much of what Fallout thrives on is 50's American culture and hyper-patriotism, but I want to see what is going on in the rest of the world. I don't know lore wise what countries are still around or may be functioning at the same level as the USA, I haven't delved into that in a long time, but I'd love to see what might be going on in Japan, or England, or somewhere else. Even Canada would be different enough. That would offer us new creatures to fight too which would be great to move on from a few of the critters like Radscorpions and Deathclaws. Maybe doesn't even have to be the full game, maybe it's treated like the expansions in Fallout 4, where you get to go to a reasonably sized new area. I think that would be pretty neat.
