I agree, it feels a little dull in the middle part of the game, once the excitement of a new and fresh open world CRPG wears off, and warts reveal themselves.
I mean, for games similar in tone and style - you don't have to look beyond Fallout 3 and 4. They both have similar takes on humor and exaggerated corporate greed.
Fallout 4 is quite colorful overall, and while the visual style in TOW is different - it's in the same ballpark, as far as I'm concerned.
Where TOW stands out, I feel, is the NPC interactions - with the varied ways you can handle quests and dialogue options.
That's about it, really.
The rest is pretty much a watered down and - surprisingly - more streamlined Fallout 3/4/76. I would never expect an Obsidian game to feel more mainstream than a Bethsoft game, but there it is.
But it isn't bad at all to resemble those games - as I love them.
