Its the replay value of the games thats so enjoyable, most particularly Bioshock where depending on the "moral" choices you make, the endings differ so much. And using the differing combinations of the powers to defeat the various enemies. Bioshock is the strongest story by far, II was Ok but Infinite was a tad too complex and the subtexts difficult to deal with until you take into account the period it was supposed to take place in. I really enjoyed the chaos of the last fight on the flight deck and again its only one you can win by combining power upgrafdes/ traps etc with the weaponry and Songbird with very effective practise. It had me sweating and gave me numb thumbs a while. I had to watch that ending twice before I understood it though, and it seemed to wrap up the trilogy nicely. I really enjoy a good story within a game and these were head and shoulders above most of whats out there. Shoot'em ups are fun but the repetitive nature a little boring after a while. I almost gave up playing the latest Tomb Raider not only because the game play was predictable but I REALLY had a problem with the grotesque ways in which she died.It actually really upset me,though god only knows why, I've played so many others,but I just couldn't handle it with this one. I'm hoping the new Thief will be as good as the old PC versions were, I loved the sneaking around ,the zero kills and the stories.Like I said,the Bioshock games were creative and thoughtfull, and I will miss new ones, whilst occasionally replaying the old
