I thought GRA was totally worth the small amount of money they charged for it. It vastly increased the firearm modding options, and I played a lot of my playthroughs as a regular guns char so it added variety in the early game. My only complaint about it was the immersion breaking GRA label slapped all over the added items, and the addition of even more fatman equipment. I wish the fatman and associated mini nuke weaponry were never in any Fallout game, and the thought of the gun runners crafting their own postwar "improved" mini-nuke launcher is just silly. People living in a world destroyed by nukes should never have even considered making more/better nukes. They would know better. In our world, 2 of them have been used on people ever, and it still scares the crap out of an entire world of people 70 years later and we generally push for disarmament and denuclearlization as a result.
