Depends on what you're into :o

Team Fortress 2 is well known for being the best free online way to have fun :3. Try it!
There's:

TAG: It's a first person puzzle solver, kind of like portal.
Pretty fun, short though. info here

And if you've got steam you could always sift through their selection of mmorpg's.
