Lonesome road, honest hearts, Dead money, old world blues.
The thing that NV nailed that 3 dropped the ball at were characters in DLC. They felt really bland but in NV,they were gripping, exciting and almost loveable.
Truely, the best times I had in NV were listening to Ulysses ramble on about bears, bulls and flags like an escapee from a veteran's mental institution for animal lovers, it was beautiful. Finally meeting Elijah in dead money and stabbing his face was amazingly satisfying. Meeting Joshua Graham face to face for the first time as he assembles and loads his .45's was both interesting to listen to, and really fucking unnerving.
Now in a larger spectrum, 3 had a greater 'goal' as many would say, but so few of it's characters felt likeable or interesting and Winter just seemed two-dimensional at times, whereas Caesar, House and yes man all had great personality and drive, as opposed to Winter's 'fucking peasants do as the enclave says and we give water alright lad?'
That is all.
I could get lost in Ulysses eyes for hours...
