It looks like Wizards of the Coast is discontinuing its support for the D&D Minis skirmish game. They’ll still be making miniatures to support role-playing, but they won’t include skirmish rules any more. My wife and I started playing the game after they updated the rules only about half a year ago. We had a lot of fun and amassed a small collection of the minis.
For actual role-playing, I’ve never used miniatures. When I used to DM in-person, it was before I had enough available money to buy minis, so we used paper-board tokens, and now my gaming group is scattered across the country so we use MapTool on the computer. So I don’t really have any reason to keep buying minis after Demonweb’s release later this year.
