which one should i complete first? i'm having a little bit of trouble here... i own both of them (both of them have all of the dlc's)

i would like to play fallout 3 because of its more immersive world for myself

i would like to play fallout new vegas for the weapon customization and personally for dead money

i'm going to play all of the dlcs too... so can some people reply here?

VEGAS VEGAS VEGAS VEGAS VEGAS VEGAS VEGAS!!!!!!!!

Did I mention you should do New Vegas?

New Vegas. The truly non-linear storyline, characters, and sheer immersive quality of the setting.

It doesn't matter. You don't need to play one to understand the other.

Fallout 3 is more fun to immerse yourself in the Post-Apoc but lacks in good writing.

Fallout: New Vegas is more fun to immerse yourself in the great writing, but the world build tends to lack outside of key location in the game.

It really depends on which one you want to prioritise.

I'd say 3 first as there is some mechanics in nv that you'll miss if you finish nv first.

Right. As i've said, i can't play Fallout 3 anymore because of New Vegas
