Fallout was one of the all-time great computer RPGs. Fallout II took it even further by adding tons and tons of extra content, much of which people are still newly discovering to this day, but some of Fallout II actually did what I feel was ruining a classic. At times, Fallout II seemed almost like a Mel Brooks parody of the original because of all of the pop-culture referenses and jokes. Both, however, were quite spectacular.
The firearms in Fallout were a little cheesy, if you ask me. The most common handgun was a 12-shot "Colt 6520" 10mm pistol with a revolving cylinder on the back, while the second most common was a Desert Eagle. The most powerful handgun in the game was clearly meant to look like the blaster from Blade Runner and was described as a handgun made from a .223 rifle, and it somehow did more damage per shot than a .223 rifle. And for some reason there was also a Broomhandle Mauser in there too.
They just seemed a little too sci-fi and not enough post-apoc, if you ask me.
