Random Thought #1: Players of newer editions complain that the AD&D charts and THAC0 aren't intuitive. How is 3rd and 4th edition AC starting 10 intuitive? Why isn't "no armor" AC 0? I'll leave the lack of a universal mechanic in these editions for another post :)
Random Thought #2: I saw a thread somewhere worried about the impact of Border's Books closing on D&D. Sadder than that is the fretting over the "death" of the local gaming store is some mixture of stupidity and nostalgia. Gaming stores are selling you the same products you can buy online, with a higher price and less selection. If you're lucky, you'll get better service, though I suspect that's the exception rather than the norm. The only true benefit they provide is impulse buys, assuming they have the impulse item in stock.
There are some smart gaming shop owners and a lot of not-so-business-smart shop owners. In a niche market, you need to be smart. What are they selling us? The same products we can get elsewhere for a better price or something else? You've lost the player-finding, game-advertising community bulliten board to forums, blogs, and craigslist. You're offering a place to play games and hangout? Run a business designed to make money off of this, not guilt/loyalty to buy product at higher prices. Rent your tables - you're already paying by the square foot of space to your landlord. A number of places offer drinks and snacks. Take it a step further: I want a gaming bar. Give me some Irish/English pub indoor, big enough tables to play, baskets of snacks, burgers, and pizza, and pitchers of ale.
Tao of D&D's charts are awesome: Equipment.
