Here's Fallout 2 on the fast track.
AGDQ 2013 speedrun by Lee. Like Fallout 1, nearly 95% of the game can be skipped...
Some other stuff to try
- Play a stupid character (INT 3 or less). It's much more fully featured this time; though you still miss out on a lot of things, there are also some unique options you can't see any other way.
- Take the more "evil" options. Work for the Duntons, join the Slavers, join the Hubologists, join the Bishops/Salvatores/Mordinos, give the "easy way out" answers to quests, etc. See just how low you can get your Karma.
- Make a character with 9 or 10 Luck and try out the Magic 8-Ball. There's a few item caches you can't access without it.
- Get Captain of the Guard. It's surprisingly tricky.
- Play a Pacifist (no kills either committed or witnessed, save for those absolutely necessary to finish the game). Harder than it sounds!
- Try out some of the other recruitable NPCs - Dogmeat, Lenny, Robodog, Goris, Myron, Skynet, K-9, Davin and Miria. Or even Pariah Dog if you're feeling really brave.
- Go into the Enclave guns blazing and try to survive. It's not easy!
- Try to fight Horrigan without the aid of the turrets. Or Sergeant Granite. Or any allies...
- Play the game for 13+ years in-game time and see what happens...
- Play with the Restoration mod. It adds a lot of deleted quests, areas and items back in.
More special encounters to see
- The Cafe of Broken Dreams, which is the Maltese Falcon building from the original game containing several familiar characters and others cut because of engine limitations or time constraints. A much more powerful version of Dogmeat is also here, and will join you if you approach him while wearing no armor.
- The crashed shuttle, which contains three Hypos that restore a large amount of HP (and was intended to contain the Phazer weapon but it wasn't included for some reason). A reference to Star Trek.
- A herd of exploding brahmin. Run away!
- A crashed whale and a bowl of petunias. A Hitchhiker's Guide to the Galaxy reference.
- The "tin woodsman" who is rusted in place and must be freed by using the nearby oil can on him, which rewards you with 150 Microfusion cells. A reference to the Wizard of Oz.
- The Guardian Portal, which has your character go back in time and break Vault 13's water chip in a rather amusing paradox. You can also find the Solar Scorcher there, a unique laser gun that can be reloaded for 0 AP and uses no ammo but only works in sunlight. A reference to the Star Trek episode "City on the Edge of Forever".
