My younger brother wants 2 play overwatch but i am still log in on a another device playing hs . Can he play overwatch at the same time when i play hs??
Not sure about other games, but if you sign in to a secondary device on the same account, the initial account will sign out of the game.
for instance, when im playing Hearthstone on my computer, and then I log in to Hearthstone on my phone, my computer is automatically logged out.
IF, you play two DIFFERENT games simultaneously, I don’t see how that would be a problem.
