@puppy@chitter.xyz I did that myself, with all the DLC of 3 and I can safely say whilst I had a good time with FO3, NV is just so much more superior in every way. Storywise, gameplay, npcs, setting, interactions... I mean I think FO3 might have more environmental storytelling in it but FONV and all its DLC were just so much better tied together and played so much more fun than 3 did. uh...NV IS ...buggy though. :| So fair warning there.
@puppy@chitter.xyz totally understand wanting to finish 3 first though. I don't regret playing through all of 3 and its DLC tbh. Sure some of the DLC was a bit...eh... but none of it was really terrible. it was fun!
