If you enjoyed the first you'd probably enjoy this. The story may be weaker but combat is much improved and I found exploring Rapture a lot of fun, even if it's not all that different from before. Definitely worth it, and I imagine it's probably pretty cheap by now.
 
Also, shameless plug time:
 
My review

Yes.

hell yes, it's awesome. I hate the whole "it's not as good as the first" shitstorm it went through, the game is still great, and the end game is awesome. And it's probably cheap these days (at least in the UK it is)

I was a massive Bioshock fan (still my favorite game this generation), and while the story isn't as good as the original, I'd argue that it's better than most videogame stories that we have to suffer through. To be frank, yes!

I wouldn't recommend it, just rent it. 

Rent it if possible, but definetly play it. The last few hours are incredibly intense and the multiplayer is a lot of fun.
