Interesting, to me two was great but not as "wondrous" given that I had already played the first, although the Big Sister was a nice touch... I've only played Bioshock Infinite once, I really should give it another go as it has been a few years, wondering how I'll see it with fresh eyes...

If you haven't played it, you've missed something to be sure... Bioshock (first game) is on my Mount Rushmore of first-time play throught experiences, even replaying (via Youtube) Andrew Ryan's opening monologue during the descent just now gives me chills and make me long for experiencing it for the first time ...
