Yeah i didnt mean any game, obviously, but the game like Bhaal tried to play for his own gains, being under threat of armagedon, personal existence in risk and all. That kind of "gods playing games with mortals" done by an evil deity for his own purposes. Sarevok was only trying to achieve godhood because he was egotistic and power hungry. It wasnt the main underlying theme of the games but one of the major consequences of the game Bhaal played. Similar to Irenicus and Bodhi, who wanted that power to escape their faiths.
But it all starts with a game one God tries to play by using mortals, giving them powers, making them think they can even cheat, use those powers simply for themselves, etc, etc. Thats the underlying theme, the source of all thats happening later on.
