For pistols "That gun" is pretty good but I mostly use energy weapons so I lean towards the YCS/186 Gauss rifle. Also for melee the "Oh, Baby!" is good. Also on the not of NV can anyone tell me if the DLC is worth it? Also how big is the file because it takes a while to Download stuff at my house?
Dead Money is rubbish. It's very hard, very tedious, doesn't give you any notable loot, and the story just isn't that interesting. DO NOT BUY.
Honest Hearts is great! A Light Shining in Darkness quickly became my favorite weapon in the game, constantly getting poisoned became a bit of a hassle though (but maybe that's just because I didn't spec into survival at all). Overall very good, I'd definitely recommend it!
Old World Blues is one of the single greatest gaming experiences I have ever had. Literally the funniest thing I have ever taken part in. The loot was also very good. Could not recommend this add on more!
The Lonesome Road is also fantastic! A very fun, tough, yet accessible challenge. Ulysses is one of my favorite characters in the game, and the loot you get is absolutely phenomenal! The story is quite epic, a standalone game could have easily been made out of it if they had stretched it out. Like Old World Blues, this one is definitely a must buy.
tl;dr: Don't waste your money on Dead Money, Honest Hearts is good but you can live without it, but do not under any circumstances pass up Old World Blues or The Lonesome Road.
