As far as I understand optional means optional not mandatory. We are no longer able to play Galactic Civilizations 2 because if the computer is not connected to the internet to activate you are out of luck. So you figure out the optional way to activate and send in the info only to get a reply stating it does not state where you purchased the game from. We did not include that info because it said it was optional. If it is mandatory then state that it is mandatory and the information would have been provided in the first place.
So now we have to wait perhaps another day before the game is playable because the info had to be sent in again including the important information of what store sold the game. Knew it was either FutureShop or EB Games but didn't know for sure till we found the receipt. We would rather have copy protection then having to go through this frustration to get a game that was playable to be playable again.
