Today’s Game is fallout New Vegas (I’m on a bit of a new Vegas bend). I took this screenshot while doing the Ghost of She quest line. I made surprisingly quick work of the quest with the Grenade Launcher (I still have over 200 grenades leftover from the Deathclaw Quarry)
Not sure how or if it’s mess up current saves or not, but if you’ve not considered it yet, is would recommend trying it A Tale Of Two Wastelands. Merges FO3’s Capital Wasteland with FNV’s Mojave via train ride. Keeps all the mechanics as well.
I did consider mods for FNV, especially ones that expand the world and lets you keep DLC companions. But I’m playing on Steam Deck, but Skyrim already was a headache for me to do, so I decided against it
