Mechanisms, Themes, Types, etc. and a Request for Assistance

We've had a number of discussions here on the concepts of game mechanisms, themes, "types," etc., trying to classify games in order to better get a grip on designing them. All of these conversations have been quite interesting.

Right now I'm working on a little web app to make Game Design Showdowns easier. As part of it I realized that I wanted descriptions for the various mechanisms, themes, etc. and so, remembering that there are some on the BoardGameGeek, went over to take a look.

Unfortunately they vary considerably in quality and, even, existence (lots are missing). When I started working through them I remembered that some of the things listed as "themes" included stuff like "card game" and "dice". I decided to reclassify such things as "types," which while being a non-ideal word, is certainly better than nothing.

Here's where I'd like some assistance: I'd like descriptions for each of these, and I'd like them to be better categorized where necessary, so I'm looking for any input you can provide on the lists below. Most of the descriptions are from the 'Geek, though I modified a number of them and added a few.

Something missing? Something in the wrong group? Something just not fit the groups? Something wrong/incomplete with the description? Have a thought for a description? Any thoughts would be great. I will, of course, pass all of it back to the BoardGameGeek guys after we come up with something.
