Energy weapons get a sniper rifle that's better than Gauss Rifle, but look up the Holorifles weapon mod location in the DLC and find them all.
There is a snowglobe worth 2000 casino chips.
There's the slot machines which gave me a ridiculous sum of chips.
There are gold bars which are worth a lot but you can't take them all.
There are two new armors which look kickass, Sierra Madre Guard Armor and Assassin's Suit.
Bear-Trap Fist+ is also a great weapon for unarmed characters.
And the new Guns weapon I hear is pretty good as well.
You can also give Veronica a new perk after the DLC.
Reward-wise though.
Well.
O:A had an overpowered tank armor, an overpowered stealth armor and an overpowered energy sniper.
Pitt had a crapload of unique new clothing and three nice new weapons for Melee, EW and Small Guns.
BS broke the game but did give us the Incinerator and Tesla Cannon.
Pitt broke game more but rewarded us with a new sandbox area which could be entered and exited at any point.
And Mothership Zeta gave us more over powered stuff.
Is it worth 10 dollars for the rewards?
I dunno, maybe. Depends on what kinda player you are and what kinda reward you were expecting.
Is it worth 10 dollars for it's setting, theme, writing and atmosphere?
You damn well better believe it.
Well pitt had one of my favorite power armors that was the one of the cow skull in the shoulder and I enjoyed the number of options you had in that DLC, and I think DLC's should have good story and good looting.
O:A had a cool story because it explained some pre-war stuff, and the looting you said.
Pitt had lots of options like I said because you could team up with slaves and slavers... and looting had good weapons and power armor.
BS had a weird story but I wanted to keep playing fallout so it was good and well looting was good too , like you said tesla cannon, Incinerator...
PL had a good story, the best map of all of them and the looting was kind of stupid I think but you could come back...
MZ had a cool story, not the best one of all but it was different and looting was great cause all the weapons and the samurai armor...
Now in new vegas DM you have great story, but you can't come back so you can't enjoy all the enviroment and looting wasn't good for me.
I accept both of this games are my favorite games but this DLC wasn't that great and if you really like a game you have to accept that there are errors too, I'm not saying this was an error but it wasn't that great...
