Guild Wars 2 is a lot of fun. The beginning would be easy to do by yourself and the story is interesting. You'd want someone to play with after a while though. I'd play with you if available but it's hard to commit to anything because of my schedule. Plus I'm on the East Coast so we're, what, 3 hours apart?
I liked Uncharted 1 but its sequel takes everything to the next level. You should definitely get it.
