Help for a n00b on 'free' games

On the Create Giveaway if you don't see your specified game on the list, it's either Steam API bug(least likely) or it was given for free. If it was free for bulk, you can't give it away. Most of your other questions probably also answered in FAQ

Free games are not allowed to be given away here because they were already given away in a massive amount and the site doesn't want the spam of levels and giveaways from it.

You can't giveaway games that have been given away in large free giveaways. Does not matter how you got it or if you already have a copy.

You can give keys that you got for free, say for a purchase bonus. So there's no problem with the Lucious giveaway.

The general rule is: if you can pick the game in a create a giveaway page, it's kosher. If it's not there, then most people just dump them in the forums.

Welcome to Steamgifts, metyGAME! ^^

1. As already answered, when going to the giveaway creation page, if the game is missing from the list, then it is considered a "free" or exploited game and cannot be given away.
2. Other ways to give away games which cannot be given away using the usual Steamgifts giveaway method, is dropping the key/link on the forum for some random user to redeem it.
3. Lucius is fine, since it wasn't given away massively.
4. All you need to know about points is included in the FAQ. You might have to review the section about points carefully and perhaps a few times to fully understand the system.

Hope that covers it all. If you have any other questions, just ask. Cheers!
