I remember it as being one of the first real FPS titles on the 360 which is probably very wrong of me (I think there was a King Kong and a Call of Duty or two) but I recall it being one of the first actual 'next-gen' FPS titles for that gen. It had really good atmosphere and the plot was really clever for the time too. I liked the shooting and I liked using plasmids: the game felt pretty open-ended with the amount of ways you could kill enemies though there were some methods that worked better than others. I still like the original Bioshock more than the other two entries in the series: Bioshock 2 felt like more of the same but with a heavier emphasis on protecting little sisters. Bioshock 3...it rubbed me completely the wrong way to be honest. I've never ever liked limited inventory in shooters and when you're playing one where a character can make the time-space continuum roll over and play dead it makes me question why Booker can only hold 2 guns at a time. Something about Columbia (that was the floating city, right?) just didn't seem as impressive to me as Rapture.
When it comes to triple-A blockbuster games, I would rate Bioshock much higher than say, The Last of Us but it's not this paragon of perfection that some would make it out to be. As a game, I have more fun with Bioshock than an indie darling like Braid or Undertale though I liked the characters of the later much, much more than any character in any of the Bioshock games I've played.
