Totally, and it was constant too! Like the ''Mechanist'' vs the ''AntAgonizer'', come on, this is supposed to be a serious post apocalypse! Or the Republic of Dave? Or Little Lamplight? Liberty Prime? Gary! The entire Wasteland Survival Guide questline!

And even when NV was trying to be serious it just came across as cartoony! Like Big Town, or the mustache twirling Mr. Burke, or Oasis, or Arefu.

Edit: okay, maybe, the sarcasm was unnecessary. I do get what you mean, visually speaking 3's tone was much more serious.

But narratively, NV's tone was far more mature and serious. To the extent that when I play TTW (which I do quite a lot...), it's the Capital Wasteland that feels like I'm playing a kids game, and I get whiplash at how much more mature the Mojave's subject matter is.
