I've been meaning to give in to the hype and start playing a Fallout game, which one would be the best for me? I've heard people say the first two games are completely different compared to the rest, and most just say to start with the third game.
if you are very normie: play Fallout 3, then New Vegas, then 4.
If you are normie but can handle jank: play Fallout 3, then Fallout 1 & 2, then New Vegas and 4. (MY RECOMMENDATION)
not normie: play in release order
Fallout 1, 2 and NV make up the west coast story, Fallout 3 and 4 make up the east coast story. Both have slight connections to each other.
TIPS FOR EACH INDIVIDUAL GAME
Overall
No, you don't need mods. Just download the things and go. If you have issues, consult PCGamingWiki's Fallout articles.
Do not, I repeat, do not interact with the fanbase unless you have to.
Fallout 1
You will hate this game on the first and second playthrough, and you likely won't finish it on your first try. But you'll find that once you get your grove the game is hard to put down. Like every fallout game it can be abused, but FO1&2 have a much harder learning curve and expect you to pay attention. If you are struggling pick
Skilled GIFTED as one of your traits. Don't take Energy Weapons or Big Guns for tag skills. ALWAYS take a high agility special. Despite its issues its still a great game and has aged better than most. oh, and DO NOT SAVE DURING COMBAT UNDER ANY CIRCUMSTANCES, YOU WILL BRICK YOUR SAVE!
Fallout 2
All of the above applies here as well. Basically a Fallout 1 mod. Much more complex and harder than Fallout 1. Unlike in FO1, you will go without a gun for a good while, so maybe think about tagging Unarmed or Melee Weapons instead of Small Guns. This game has the most companions and is at its best when you play into its post-apocalyptic road trip with all your buddies, so take a high Charisma stat if possible. Way longer than Fallout 1 but also more bloated because of it.
Fallout 3
Bethesda's first entry in the series. Way way easier than Fallout 1 & 2. Very odd in that its basically Fallout 1 in 3D. (despite this being a sequel to FO2) You can tag any skill or special and be fine, as you'll get pretty much every weapon type within the first 3-4 hours. Unlike Fallout 1 or 2, don't try to follow any character creation guides. When you first walk outside to the first town (megaton), find a rock near the backside of the town exterior, you'll find some early game goodies in a hollowed out rock. Fallout 3 walked so NV could run. Play this before NV as it might be hard to go back. 3 has a better overworld for exploring though. Don't miss out on the DLC.
Fallout NV
Basically the real Fallout 3, made by mostly Fallout 1&2 devs via Obsidian. Fallout NV is to Fallout 3 what Fallout 2 is to Fallout 1. FNV is a gameplay sequel to Fallout 3, and a narrative sequel to Fallout 2. All you need to know is don't go north out of Goodsprings unless you have a death wish. If you find that about halfway through the game your save wont load (infinite loading screen), start a new game, skip the cutscene to load into the actual game itself, then load your other save via the menu. Just enjoy the best game in the series. Don't miss out on the DLC either.
Fallout 4
Bethesda's second entry and the most normie game of the series, don't go into it expecting it to pick up on any of FNV's lessons. Don't expect it to pick up on any of Fallout 3's either. Special matters a bit more than the other games as for whatever bright reason they dropped the skills system entirely. Basically a direct sequel and a gameplay "sequel" to Fallout 3. The only recommendation I have is this
load accelerator plugin, as the load times for the game are atrocious without it. I don't know what black magic they made with this, but it works, and it works well. Please play the Far Harbor DLC as it shows what 4 could've been with a competent writing team.
