Should I activate my game that I won?

Its against the rules to NOT activate it .

You either activate it yourself , or ask the GA Creator for a reroll .

You CANNOT give it away to anyone , friend or random person ... you Must activate it yourself .

Also , i suggest editing that topic , and closing it asap ... since you will get in quite a few blacklists for it .

No you cannot give it to another user, read the faq, u need to give it back and chose to reroll the winner, u can enter in that giveaways becouse u dont sync the account again, remember to sync always the account, when u get new games

Just ask creator to reroll,that's the best option

Entering the Collection/GOTY edition of a game if you only missing one dlc is a dick move

Either tell the GA creator to ask for a reroll or activate it.

you entered just for one dlc? wow.

Dungeon Defenders is kinda tricky, it will always let you enter the giveaway even if you own all the DLCs (tested personally). So activating the game on your account will simply be a waste, better ask for a reroll.

Re-Roll and pay attention to what GA you enter and make note of games you have that may not be marked as owned due to issues i have a few games i own but still allow me to enter GA.

Not worth a risk of a ban or other restrictions to give it to someone else,just tell the creator to re-roll it then you will be a alright.
