Aaron, I'm trying to remember the names of some of the old article series that ran here. I know that Seth's was Dreaming Out Loud, and of course mine was Game Ideas Unlimited; but a lot of them had banners when they first ran, so in the conversion to the new format the ubertitles were lost and only the episode titles remain.
I vaguely remember that there was a Game Design Journal, or something close enough to that which was frequently abbreviated GDJ, and there was another column called Game Design Step-By-Step, but I'm not sure whether that ran concurrently or came from somewhere else. Wick wrote one of these (the development of his OrkWorld game), and I think the other was Skarka. Skarka had a second series later, concurrent with Game Ideas Unlimited and Dreaming Out Loud, at which time you also had the Thursday column and there was someone else whose name and series names I cannot now recall who ran on Monday (which if memory serves means Skarka was on Tuesday and Seth on Wednesday, but I'll see that when I get there).
If you remember the names of any of these columns, I'll tag the articles accordingly as I go.
Thanks.
