I've been looking around for some ideas about mechanics. I first looked on boardgamegeek under mechanics. The list they have is a lot smaller than I had thought would be there. I've also found a blog on Board Game Designers Forum by KrinkleChip about game mechanics. And of course, there is the wikipedia article. I've also come across some pretty good ideas regarding putting together a nice database of mechanics in forums here and there, but I'm unable to really find anything like that currently. It would be a huge undertaking.
The reason I'm looking into all this is that, with the restrictions I've placed upon myself (discussed here), I'm working on a card-based game (calling it Korihor: Anti-Christ right now), attempting to keep the components down to cards, one die, and some tokens. In this attempt, I'm trying to become more familiar with the kinds of mechanics that have been implemented with cards before. Having that kind of knowledge definitely provides a great benefit. In fact, I think I'm going to join the effort to provide such a thing to others. Mainly because it would be a great resource, but also because it will help give me a lot more knowledge of game mechanics.
