2000 vs. 2013 vs. 2020 vs. 20??

[Neal5x5]

It's pretty obvious from reading this forum that the setting history of the Twilight: 2000 games you're playing now has been tweaked to fit your group and style. What about the actual year of the game? I'm curious to know if more people are playing a near-future version of Twilight or if they are playing a year 2000 game. I think there's good reasons for both, but I'd like to get a better understanding of why people choose to run games set in either period.

Forgive me if this has already been covered in another thread - I'm still pretty new here.
