Simple question, can I use the Old Base Game Yog-Sothoth with the Arkham Gates expansion and if so, if an invesitgator fails an Other World Card with a gate on it would you then just remove the gate on the corresponding Arkham Adventure card as well?
Can Old Yog Sothoth be used in Arkham Gates?
Here are the answers on the BGG thread:

Essentially: Yes, you can use any of Yog's three versions; and the gate is removed and sealed .
