What can you do with the other copies when you win , for example, a "3 copies" giveaway?

Selling them to a keystore for 1 copy of Fortix?

Best deal eva.

Let's say it takes you 5 min to register a new mail addy and another 5 min to create a Steam account and register the game key.
Then you do all the coal achievements on F2P games, which take 5-20 min / each (let's assume 15 as an average; let's assume that there are 3 F2P games with coal achievements; let's also assume you don't use any 3rd party software to unlock those achievements). Another 5 min to transfer the coal from this account.

Then it would take you 1 hour to get all this coal for one of those accounts.
25000 hours = 1'041 days = 2.8 years

"I'm not stupid, I don't do that manually" - okay, so you automated the process, you don't play the games and registering emal addy, steam account, adding the game and transferring the coal takes you 2 minutes total.
That would still be 34 days.

Nah, I doubt anyone would do that :3

Ok, thank you.
