I finished today Fallout 3. I have just one thing to say : the end is epic. I won't spoil it but that's really an impressive piece of fireworks and all.
It's really sad that the main quest is so short, for it's   really   interesting.
I'm thinking about starting the game from scratch once again but this time with a bad guy ^^
Last words :
Go Liberty Prime, pwn those Chinese cocksucking childloving communists!
