I am running a PBP game and want to find a good interactive map solution. I have an older PC sitting doing nothing and I was wondering if I could just keep a game session open on it indefinitely. What I am really after is an interactive map that players could access when ever they needed to. Is there a limit on how long a game session can be? Is it a huge resource hog that will eventually just grind to a halt? Has anyone done this with any success? Thanks for your answers.
