Everything is playing, even if it’s just trying to find a system or generating a character and moving on.

I’m working on an online character sheet for BECMI. It will save to the web browser’s cache, so be careful not to delete your cache, or at least print out your saved character to make sure you don’t lose your stats if you do clear your cache. I’ll add the link to this post when I have the page available.

UPDATE: BECMI Character Sheets

That link will take you to the BECMI Character Sheets page. You can store multiple characters in the browser cache and switch between them quickly. If you want to back up an important character, create a PDF out of it with the button at the bottom.
