Things I have done in Fallout 3:
1. Met a clan of vampires and received a bonus perk that gives me extra health when I drink blood.
2. Made a Goth chick fall in love with me and give me random supplies and health packs.
3. Made a flaming sword out a lawnmower blade, motorcycle handle and a gas tank.
4. Killed a bunch of fire breathing ants.
5. Got implanted with the genetics of a fire breathing ant.
6. Blew up some heavily armed mutants with an explosive housed in a lunch box.
7. Convinced a guy to stop abusing drugs and then stole all his meds.
8. Saved a village from mutants.
9. Stole a ton of stuff from that same village without anyone noticing.
10. Got radiation poisoning (and a mutation), fell off a building, got blown up by a mine, and almost got killed by raiders all in the name of literature!
I love this game.
