Yeah, the core set of Fallout is enough to play with. The only issue, as with any core set for miniatures games, is that you'll find that you will want more options. You can equip the characters differently to add more variety and you don't need a ton of models per side.
That said, I like having more options for list building. Different characters/units can change of how games feel, as besides different stats, there are some cool abilities that are character specific. And certain scenarios may also require more lockpicking or computer hacking the firepower.
I have a lot of the survivors/settlers models, as well as Super Mutants, Brotherhood of Steel and more recently, a bunch of Raiders. I've also got Radscorpions, and Radroaches. 3 Assaultrons, 2 Protectrons, a Sentry Bot and Eyebot round out my robots.
There are also the machine gun turrets and laser turrets. There are even rules for vehicles and having them explode.
Lots of cool stuff.
I'm almost done painting my 2nd set of Imperial Scouts. Should be getting my Imperial and Rebel unit upgrade sets soon, as well as operative Luke and Vader, and the Escape Pod set with R2D2 and C3PO.
While I don't get to play Legion near as much as you do

, I do enjoy painting the models.
I've been playing a lot of Marvel Champions LCG, about 55 games in so far. Eating away at my hobby time
I am also running a demo of Fallout Wasteland Warfare at a local convention at the end of the month, so I've been working on playtesting a scenario for it.
