Alpha sheets can now be added to games via the edit option in the alpha sheet display. In addition, statblock embedding should also work for the [sb=show][/sb] tags. Any problems, please post in experimental features with links to the sheet and the game.
One Roll Engine. Wild Talents is the most easily available game using ORE. I mentioned it earlier because I think it's a neat system. However, it's also a bit tricky to build powers for until you get used to it.
