Just show off... Tell me what your house looks like, your trophies/achievements and weapons/armor. For me I've been playing about a year on both games. On fallout 3 I have a 65% trophie progression on the ps3. I have all bubbleheads and just about all weapon/armor from all DLCs but the Pitt. I'm the highest level.
How bought you? I also have my house at megaton and I'm very good karma.
