I have the same problem! I never check the forums but I keep checking because I'm daydreaming about the Stories I could tell with the Foundry! Hopefully when they say weekend they mean Friday Night! Please get it back up! Please!
I seem to just have gone into Foundry withdrawal or something. The main game no longer holds my interest. I want to go and build missions, write interesting storylines for those missions! I want to build, create, it's crazy! I'm literally finding myself daydreaming about when Foundry will be back on and I can set back to work on finishing a mission so I can publish it.
I'm sure this is a phase that will pass... but for now... GET THE FOUNDRY BACK ONLINE!!!!
