Bioshock, Mass Effect, or Ceville?

All 3 of the games are $20 on steam. Which one would you recommend and why?

Well I intend to pick up the others later on (hopefully when they are on some kind of holiday or weekend deal). Do you think mass effect will take me longer?

Mass Effect for me, it took me a little while to get into it but once you get your head around the story and the gameplay it's a fun game. A lot of people compare it to KOTOR which is fair enough since it's from the same studio but the game mechanics are a bit different. Game for game KOTOR is the better game, firstly when it was new on the PC it looked great and didn't require expensive components to run smoothly and look nice. Secondly the KOTOR was a longer game, when I finished Mass Effect the other week I couldn't help but think the game was a touch short and padded out a bit with needless and repetitive side quests that really weren't that interesting.

As for Bioshock................a shockingly bad game. The gameplay is awful and no matter how long I played the game for I just couldn't get used to it. My biggest gripe is the clunky way you fire you weapons, it just feel or look like your firing your weapons properly compared to a normal FPS game. On the plus side I loved the art direction of the game, it kind of reminded of Fritz Lang's Metropolis (I doubt you would have seen Metropolis since it's a film made over 70 years ago. Rather then site through it, search on Youtube for 'Queen - Radio Ga Ga', their video was based around Metropolis and that will give you an idea of what the game looks like).

The only problem I had with Mass Effect is I got so sucked into the story, I did virtually no side-quests on my first run-through. The biggest plus: immediately after I finished I started a new character and played it through again. Spent ~21 hours on the first playthrough and ~34 hours on the second.

Also, it's got huge replayability. Different character classes, and you can unlock abilities that'll cross from one to another.

Yeah I purchased Mass Effect, but I know I will nab Bioshock later on.
