I was waiting for someone to be insane enough to even suggest that the MGS storylines were anything more than sub-par, Steven Seagal-esque trash. Quite frankly I think the plotlines are sub-par, Steven Seagal-esque trash, and the continued devotion to the series baffles me.
In terms of a storyline I'm quite keen on the ones found in both System Shock 2 and Bioshock, both told in the same drip feed, piece-it-together manner that I really enjoy. Finding out what happened is half the fun, you're not just shown it all. Plus they both have neat plot twists that creep up on you quite subtly, though you can spot the patterns...sometimes. (SPOILER)That whole "would you kindly" thing really caught me off guard and both enthralled and freaked me out in equal measure.
