Having dropped New Vegas in the past due to lost interest, I decided to try this game out finally since a friend of mine was having a fallout 3 playthrough himself. It was it 8 bucks, so I figured why not. I have to say, I put way more hours into this game than both other Bethesda games I’ve played through (Skyrim and Oblivion) before even finishing the main quest line. The combat was excellent in my opinion, and I (seem to be in the minority of people who) really liked the story. The choices it forces you to make sometimes really had me feeling emotional at times. I also played it with some minor mods installed, just some custom outfits and real world guns for immersion. Nothing to break the story or anything, though there are a few DLC sized mods I’m eyeing up to play in the future. Overall I seriously enjoyed this game, I’ve noticed online it seems to be regarded as one of the least popular mainline games but I think it’s become my favourite Bethesda game I’ve tried so far honestly. Seriously recommend anyone who hasn’t played this yet to at least give it a try. It really pulled me in.
Edit: Since I’m done with F4, got New Vegas running with some nice mods to add gritty aesthetics and real world weapons. Giving it another try 6 years after I initially tried it and so far I’m way more into it!
Edit 2: more specific context
Also, the only temporarily impactful decision you make is which flavor if the final mission you’ll do. You don’t actually have to choose one until the very end. You can somehow be not just friendly, but high rank with all four at the same time, despite the conflict of interest.
They make you think your making choices sometimes (though honestly rarely in F04 because of the dialog system you mentioned), but you never do really. It’s an alright survival shooter thing, but a bad RPG. You choose abilities, but you rarely choose a role. You’re given your role at the start, and your only choice is to follow it.
