I've been working on a 4E project which I'm pretty excited about. It should be a nice ease of use upgrade for players and GMs alike. Unfortunately right now it's just a pile of .NET code and XML. I'll post screen shots of it once it's usable in FGII.
In the meantime here are some screen shots from last night's session. More details can be found at the Obsidian Portal site for our campaign, once I get to updating it.
