I missed on S1 - most would have as no one knew what the hell was happening
I missed on S2 - timing and lack of a "proper" kiosk near me means relying on someone else...never good
I missed on S3 - mic issues and then of course timing with that big ole circus
that IRC has become
I unlocked S4 (#39) - Talked to Volman and got the link about 15 secs after it had been posted to IRC
I missed on S5 - Well, this one was a bigger circus
...My wife and I seriously contemplated cashing in our "rewards points" for stay in NYC and right now am VERY glad we didn't (my work is all remote oracle dba, so all I need is my laptop and internet). I am still po'd about the coordinates thing...not mad at the other people that did unlock...that is their way and they deserve the accolades...we thought we had someone there, but we didn't have them EVEN CLOSE to the right place thanks to the coordinates being wrong.
All in all it is fantastic and I am still eagerly awaiting clues for this thing to really get turned up.
On a side note: I would not be surprised if there was "end game" swag, but not server specific swag for the S3, S4, and S5 peeps. ILB didn't get enough people b/c I think no one saw the point, especially with the lack Halo universe tie-in. Iris quickly got a huge following when people thought that there were prizes to be had (tito). Also, think about how quickly the rest of the servers opened, not allowing people to break away if they thought there was to be no swag. Think if it had gone 20 days between servers...how many less people would there be on S5 when by the time it opens, S3 people still hadn't received anything. I know, I know...for the story...but Bungie has always tried to get the people who don't care about the story too...the hardcore gamers and others you probably never open campaign (except for achievements now on 360).
