January 28-30... for college students, that is around the beginning of the Spring semester.
February 25-27... that misses out on Valentine's Day. Think of it! If the jam was for the 12-14th, then the regular folk would probably devise a number of demented collaborations parodying the holiday of romance and love (or come up with something actually sweet for a change). Since it is a game jam, they would also be interactive.
March 18-20 hits right around St. Patrick's Day. Few days later is the equinox.
April 15-17 is too far from Pico Day for it to be relevant/thematic toward the titular date. Bump it up a week.
May 13-15... when's Mother's Day?
I don't care when the June Game Jam takes place.
And I can care even less about Comic-Con. How about this: the Newgrounds folk conduct research into the local Cons in their areas, and construct a Flash about them instead! Or Cons in general. There is a wellspring of satire to be found in any convention, much of it scathing.
I have no objections to August's dates.
9/11 will definitely be a "Yank" thing, especially since that would be the tenth anniversary. Under no circumstances should that be switched. Before anybody protests, let the jam be a free-for-all and let the participants' sentiments guide their creations. There are bound to be a few who recall that day.
I am so fackin' sick of zombies. I really am. What happened to Lovecraft's Mythos or Carmella or any number of nightmarish horrors that used to mesmerize the collective imagination of the Newgrounds audience? No, it's all about sucking brains and endless gallons of gore! BORING! The only Gore I appreciate is a Bastard with an electric guitar, and he will sic his Slurpers of Death upon all of you zombie-obsessed zombies without a single thought otherwise.* Find a theme to fill my sights. Otherwise, go peek around in a crackhouse!
November... ah, I don't care.
The December Jam doesn't step on anybody's toes, either. A thematic jam any closer to a date like that is just not worth the time for some people. It doesn't need to change.
That's my take on the tentative schedule... it looks okay but could use a few extra tweaks.
* - Look up "Attack of the Slurpers of Death" in the Audio Portal; it leads you to ManSpider, GoreBastard's ancient alternate account. Gratuitous comic horror mischief awaits.
