How do u delete a game?

On the games menu, hit the 'i' (info) button and click archive

Hello,

Stangetalent is correct. Go to your main account, go to "My Games" in games menu, press the (i) button and click "send to archive" no longer log in and it should drop from your games eventually, I would say if you plan on leaving message the games Game Admin in diplomacy and ask him to remove inactives when you turn inactive, that way it will drop out faster from your games list.
