When the RC came out, I'd pick it up everytime I'd pass a book store, but I never bought it. I played more sophisticated games now.
I played a on-a-lark AD&D2e game & was surprised at how simple yet satisfying it was, but I still found it obsolete.
When 3e came out I was excited. This was the D&D I'd always imagined creating myself. The best of AD&D1e & the RC along with those "modern" improvements from Gurps, et al.
But, month by month, I became more & more dissatisfied.
I read Gygax's tales of the early days in Dragon magazine. They made me want to game more than anything had done in a long time. I sought out more tales & found some of Kuntz's recollections. Then Michael Mornard's. (& a couple of others)
Following Gygax led me to Dragonsfoot. I wondered, why would these people be playing a game I gave up as hopelessly obsolete c. 1990? I tried to find out.
I started to remember the wonder I had early on, before I started to find faults with the game.
I discovered a new ways to look at old things. Ways that I liked! I started to ask, "Why is the point of this rule?" instead of "Why is this rule broken?"
Now, when I look at 3e, I see fixes for things that no longer appear broken. I find fuel for my rule-lawyer habit. (Which I no longer see as a good thing.)
Nostalgia. Being older & having less time & finding the simpler game fits in my life better. A change in my tastes in general. Those are a few of the reasons. See my website for more...
