Because so far it seems like it's generic modern brown post apocalyptia. And I would really love to see a retro 80's vibe in there. Leather clad mohawk wearing ruffians with laser guns > generic bandits.
We haven't seen any areas that would accomodate leather clad mohawk wearing ruffians with laser guns. Oh yeah, and laser guns were never used by leather clad mohawk wearing ruffians.
You sure you're looking at Wasteland, not the Leather Goddesses of Phobos or somesuch?
There is definitely a lot of 80s influence, yes. It'll be particularly outspoken in specific factions that I can't name >_>
But yeah, it's there. It's not super-explicit throughout the entire game though, not that front and center, but as WUE mentions on the frontpage, you can even see it in the lighting.
