I start out with heading to Klamath, doing the usual stuff like picking up my buddy, doing miniquests, visit the car wreck etc. I then save and head straight to Navarro. Yes, i said Navarro. I infiltrate the base like you would do later on and i pick up the Advanced Power Armour (still at level 2, maybe 3) and the vertibird blueprints and the key thingie. I then head over to New Reno and pick up a sniper rifle and maybe a .233 pistol. I do the Boxer quest and some Mafia quests(i get Myron) while i'm at it. I'm now adequately armed. The Voice Recognition Module is also important.
I hop over to the upgrade-for-free guy and upgrade my buddy's stuff. I go to Vault City, get the fake pass and pick up Cassidy. I do the plow quest and the beer quest, too. I then proceed into the vault(everyone knows how to exploit the bug, right?) and loot it. I use Mentats to boost my PER to 10 and then use the computer... This allows me to add a lot of locations to my Pipboy.
I have a chat with the 1st citizen and do the gecko quest and i also the my Super Toolkit for the car thingie. After i've fixed the plant(which is damn easy) i head back and become a citizen.
Time to go to NCR. I slaughter the Raider Base while i'm at it. I also stop by Modoc and get Marcus. At NCR i sell my stuff to the midget, buy a LOT of .233 ammo and steal a Bozar for Marcus. I do the usual quests(kill slavers, chip for Tandi, etc).
I stop by Vault 15, do the quest and locate vault 13. Then it's time to get the GECK. I fix the computer for the Deathclaws at V13 and pick up the GECK along with the IFF(vital for the tanker).
I go back to the village in order to trigger the second part of the main quest(i'd rather skip this, but i can't go to the oil platform otherwise).
San Francisco is next on my list. I pick up the Gauss Gun, get the Jet Antidote, pick up a lot of ammo, stimpacks etc... The Kung Fu quest is also pretty easy, so i do that too. I chat with the BoS guy and get the quest for the blueprints. I got them early on so i just show them to him and i'm in. The weapons are good for money=more ammo and stims. I use the modules i've found, usually STR and INT. The guys with the Emperor(whatever they're called) want me to kill the Hubologist leader and Give them the vertibird blueprints in exchange for letting me access the Emperor. Fair enough. I join the Hubologists and kill the leader with the Super Stimpack exploit(everyone knows how it's done, right?). I hand them the blueprints and bam! I have access to the Emperor. One fuel transfer later i head to the tanker, save the girl(lots of EXP for me) and install the IFF device using the key i picked up at Navarro earlier on.
Time for the final level. I use the stealth approach, leaving my party at the entrance... The rest isn't so hard. I convince the scientist to release the FEV, kill the president(his key thingie is nice for the end boss) using the SSP bug and set off the nuke. I go back, use some Mentats to raise my CHA to 10 and convice the team of soldiers to help me kill Horrigan. The key from the president is used to turn the turrets against Horrigan. The rest is very easy... The team moves in, i snipe with the Gauss Gun and the turrets help too... Horrigan falls pretty quickly.
I go to the exit, and i'm done. I've finished the game.
I'm not going to list every single quest i do, but i do everything i can in each city i visit before heading on. Random encounters are pretty self-explainatory.
