I thought Fallout 3 was pretty good until I played New Vegas and realized that it fixed nearly every single thing that sucked in Fallout 3. It was AGES before I went back and actually beat FO3.
Also yeah the South Park RPG thing is a waste considering South Park is a vile piece of shit that reinforces some really horrible viewpoints. There's not even any hope that they might try to take it in a different direction considering one of the character classes is JEW welp good job everyone.
My experience of Fallout 3:
U start the game as a baby. Fuck you dad, I hate you dad. Try to kill dad.
Can't kill dad.
Start the game in a stupid ugly town.
There is only one other real town, populated by rag dolls you can't kill.
There's a pimp, for some reason, and an offensive follower character who's a slave who keeps saying "You can take anything you want, honey" over and over.
Find dad in virtual reality. I hate him and want him to die. Try to kill him again, you can't kill him. Why does he have a british accent.
When he finally dies it doesn't make me feel any better because the Brotherhood of Steel are so stupid.
You literally can't kill almost any of the NPCs, or even put slave collars on them.
