Oh, I have a fusion core location.
Go to Concord, and go to the hole the Deathclaw came out of, yeah?
Inside of that hole, there’s a small pathway that leads into the Concord Civic Access. In the Civic Access, there’s no really strong enemies (mole rats, rad roaches, a singular living mirelurk) and if you just go WEST in the water- thing, just totally west, you hit like a wall. On the left (I think) there’s a Vault Tec Lunchbox and a Fusion Core hidden behind a pole. It took me an hour to find them, but that’s because I have crap vision IRL and for some reason I thought I’d try to play without my glasses.
And I feel you with that, man. I love games, but the only “open world” ones I’ve finished are Spiderman 2 and Pokemon Scarlet/Violet. The rest, are either just so freaking long, or the ADHD has me and I can’t go a single step without getting distracted. the Golden Rule of the wasteland applies to every single open world game. TOTK? I’m not great at the combat, so fighting Ganon is gonna be a bit…
BOTW? Even worse at it than TOTK.
Mad Max? It’s really, REALLY, long apparently. Also, shinies.
AC Origins? Less than the two of those, actually. The thing with Origins is that it’s apparently really long, but it’s really good. There’s quite a few shinies, but for me there’s sections of the game that say “dude it ain’t time for this stuff yet, you under leveled” and then I go upgrade something and come back swinging.
AC Valhalla? Sold it. Never again. I accidentally deleted my 80+ hour save file NOOOOOOOO
