darkknight9174: One thing that is annoying, but certainly not the entire reason for it being boring is that I've got Vic and Lenny as companions and they're equipped with knives and no armor. I've got a pistol with 24 shots and a spear but that's it.
This definitely should not be the case when you're in Gecko/Vault City.
By that time, you should have at the very least hunting rifles, magnum revolvers, (great weapon, you can buy it in Den.) submachine guns and plenty of ammo. As well as metal armour or leather mk2. (You can get some in Modoc.) Your companions should have leather armour at the very least.
Note that you can equip your companions: talk to them, select the "trade" button, give them stuff, press the "tactics" button, and select "equip best weapon/armor." In that window you can also select stuff like when they should run away, how careful they should be when shooting, what drugs to use and when, etc. (Fun detail, though: the options are limited by the character's personality. So Vic will flee a lot faster than Sulik no matter what you select. And some characters just suck with guns and won't be careful when aiming bursts no matter what. Idiots.)
Edit: Oh, and companions are also limited in what weapons they can equip. You can ask them what weapons they can use. But note that this is actually linked to the character model's animation frames. So when Sulik says he can use submachine guns, he means he can use any big single handed gun that *looks* like a submachine gun. Including stuff like 14mm pistols or the .223 pistol. Which are much better choices for him, since the odds of him going trigger-happy and shooting your allies, innocent bystanders, or yourself are much lower. Not to mention the money you'll save on ammo.
Incidentally, if you want a more competent companion instead of/in addition to Vic or Lenny, look around Vault City for an old guy named Cassidy.
If money is the problem you should probably do more side quests (Talk to everybody in the towns. Also note that many/most quests have multiple possible outcomes.) and loot and sell everything. Use NPCs as pack mules.
One easy, if slightly boring, way to catch up equipment-wise is to wander around until you find an encounter in the vein of "group A fighting group B." If you run away quickly at the start of the encounter, most NPCs will kill eachother and leave a bunch of equipment for you to loot. This way you can find high-end combat shotguns and the like. Which, honestly, will break game balance. But eh. Fallout isn't very balanced to begin with.
Of course, the game may still not be your cup of tea. But I do think you're experiencing more frustration than you ought to by now due to being outgunned.
