As far as Fallout specifically goes, I can't name a single thing.
THIS
Now in is own merits... Hmmm... Well, it did bring Fallout and the "Bethesda formula" to the popular scene and not with much marketing, but looking with hindsight it wasn't such a good thing, as it ruined the core and heart of Beth's franchises.
- In a more positive view, it does present itself really well following the classic Fallout's principle, in exploration-progression wise i mean.
Probably these are locked, but there is a huge deal going on about finding places X and Y, like Vault 87, but after subsequent playthroughs you can get there no probs. This was lost in Fo4 as there was either none or barely any misticysm of hidden locations, main or side ones.
There's the friendly lil' town next door to get you started with the lore and quests, although that's the "Startville" trope of RPGs anyway.
- It just needed a push or an electroshock to the writer to make the Enclave amiguous and not need to be left for CT.Phipps to headcanon over, but that's not a trait, just a Maybe
- NPC's had SOME character to them. Of course, that means that i somewhat liked James a bit in the way that one can feel however they want about him and it shouldn't be out of place. Him getting himself killed for a retarded reason for a stupid cause belongs in the Story department.
- Charon is a companion that can throw grenades properly for once.
To say more i'll have to wait for that TTW update, the game is mostly blurry on me.
