A comparison with Bethesda's last RPG, Oblivion, is inevitable, so let's get that out of the way right now. Fallout 3 is very, very Oblivion-like, with some of the same issues such as NPC pathing, but it's improved in several areas. The visuals are more detailed than Oblivion which is saying a lot as Oblivion was one of the most gorgeous games to ever grace a console or PC back in 2006, but the most dramatic improvement is in the voice acting. Oblivion was lacking in that respect, and it always sounded like Bethesda grabbed three random people, tossed them in a sound studio, and forced them to recite endless lines of dialogue in an attempt to populate an entire world with a variety of voices. In other words, it fell flat. Fallout 3, however, is populated with a rich cast of characters with voices that seldom sound similar and this goes a long way toward extending the credibility of the world.

Is the game fun, though? In many ways, yes. But the fun tends to come from random side-quests and odds and ends that you stumble across through exploration rather than by following the main story arc. For example, during one of my wanderings I came across a small settlement with the unlikely name of "The Republic of Dave." This guy Dave has declared this tiny town (population 5, plus children) its own sovereign nation. Apparently it used to be the Kingdom of Tom, who was Dave's father, but Dave decided to change the system of government to be more progressive once he inherited the kingdom. In this settlement, the dialogue options are hilarious, and you can attempt to rig an upcoming election and toss Dave out on his ear. Or you can walk through the Republic with an automatic shotgun cutting down its inhabitants like wheat (on a side note, if you make your intentions to take over the Republic clear, the person you're talking to will run away screaming "Communist! Help! He's a communist!!" Classic).
Morality plays a role in Fallout 3, and you're usually able to choose a "good" or "evil" solution to most of the challenges you face. While in most cases this doesn't have a significant impact on the world, in others it can change the world dramatically, and sometimes even the landscape itself. There's definitely a joy in being able to gun down virtually anyone you come across, and admittedly I spent a good hour reloading the Republic of Dave and murdering its population in hilarious ways just for my own amusement. This brings me to the combat: It's pleasantly gory. Limbs rip off from their sockets and fly across the room from the impact of bullets and explosions, and bits of bone protrude from muscle tissue. While it's a very satisfying experience, it's certainly not for children.
In summary, Fallout 3 is an exceptional game with a variety of flaws that detract from but don't ruin the experience as a whole. There are a lot of things I'd have done differently, but it's a solid game that should be experienced regardless of what system you play it on. Party faithfuls of the original Fallout games will no doubt complain that Fallout 3 is more like "Oblivion with Guns" than a true successor, but Bethesda treats the series with respect, and does a good job overall of blending the atmosphere and systems of the original games with its own RPG engine. I played both the 360 and PC versions, and if you have a rig that can run the game, I highly recommend the PC version for its faster loading times and potential modding possibilities if Bethesda ever releases an editor, but failing that the game is nearly identical on consoles and still provides a fun experience.
