heres my FOM for NV
not much but i haven't really played the game since its release
i did a 10 LUCK character which is incredibly overpowered and fun, gambling is easy, especially if you know how to play caravan. i started with a 9mm pistol and put a scope on it, the luck makes you crit basically any time you get a stealth attack, i was 1 hitting low-level creatures and bandits with just that pistol. later when i got my first sniper i was literally 1 hitting deathclaws. only be sure to have some steadies because your scope swing is ridiculous.
i rushed speech and then lockpick because those are the two most overpowered, i recommend using intense training perk to get more CHARM
oh and Boone's beret gives like +5 crit chance so get that too
visit REPCONN HQ early on in your playthrough
i've done the main mission (anarchy end) and did dead money which was a lot shorter than expected
