Here's what I'm doing today:
Came in at 8 AM, worked a bit on Keep on the Shadowfel.
At 9, met with Bill to talk about the adventure, took a ton of notes.
10 - 12, worked on the Shadowfel outline. Basically, I made a big table in MS Word and used that to plan out each page. We need to do maps and art for the book soon, so it's important to plan out what we need to depict and what maps we need.
The adventure is designed to show off all sorts of 4e stuff. It serves as a quick start guide, but while parts of it are there to teach rules, it's a full-blown D&D adventure. You'll need to roleplay, figure out puzzles, out-think the bad guys, and everything else you need to do in D&D. Oh yeah, and there's tons of monsters to fight.
I'll probably be here until 6 tonight. This afternoon has a meeting on CENSORED and mechanics for ALSO CENSORED. One of those two went from a pile of no work into a pile of maybe a lot of work. The other one was mostly solved yesterday, but that assumes that everyone in the department thinks we're not being stupid WRT our solution.
Today, the next set of dungeon tiles arrives in the product room. At WotC, employees have a budget of product points they get to spend each quarter on stuff we make. I'm planning on getting some tiles and minis for myself, plus I need to figure out how many points I have available to buy stuff for trades. With luck, I can lure the dudes at Paizo to trade me some of their cool-looking GameMastery modules for some WotC swag.
Oh, and who has four boosters of Desert of Desolation on his desk? Your friendly neighborhood lead developer, that's who.
