I’ve been somewhat busy due to university and visiting my parents for (now third) consecutive weekend. I make no promises, but more posts are possible in the near future.
1. Reynard’s blog on Enworld has material on sandbox play and random encounters. Of especial notice is this post. Unfortunately the RSS feed does not seem to be working.
2. Jonathan‘s rpg blog anthology project. If the project works, more people will be able to read the ramblings of random rpg bloggers. If it does not, J will hopefully still list the nominated blog posts or some best-of summary, so it will still be a way to find good posts. Contributing takes little time and gives you an excuse to re-read a few good posts, if you are so inclined.
The following are links to my own projects. So, not much to see, unless you are especially interested in my projects. Both the wikis have an RSS feed available. There is a page about wikis, including a link to Abulafia, which you should use.
3. Wiki of persistent fantasy rpg / In a Wicked Age clone / my default no-prep game.
4. Wiki of the dungeoncrawling rpg I have GM’d a few session of, and have been developing during my free time. Rules update is the most relevant page there. In the unlikely case of some reader wanting to contribute, ask via email, blog or the option in the wiki.
