What makes me a unique halo fan?
That's a tough one. I don't think I'm that unique.... But I have read the books about 3 times each, gone through the graphic novel a half dozen times, beaten every level of Halo solo on every difficulty on the X-Box I won right after I started at my University and am still working my way through Halo 2.... I bought a 360 and a HDTV not just because I wanted them and Halo 3, but because I'm starting to acquire personal belongings for moving out of my fraternity house.
So far I've spent about 36 hours reading up on all the information here and abroad about developing your own costume armor, acquiring and familiarizing myself with Pepakura, scaling and tweaking the ODST files so that I can print them.... Then failing to save the microsoft print file correctly. >,<. I've developed a logo for the ODST division of the 405th, am working on versions for the marines and Spartans, come up with the ODST creed from the Paratrooper's creed....
I frequent the Bungie forums, have read a lot of the fan works for Halo that are out there (good and bad), have watched 60% of RvB, am trying to find other Halo machinima in my free time, and am slowly writing something based in the Haloverse.
Yeah, sure, I've bought all the Halo games and a lot of the other gear, but.... Eh. That's not exceptional. A lot of people that just like the game for what's in the game have done likewise.
Of all my friends "IRL," I probably know the most about the expanded halo universe.
