The reason I'm writing this thread is that these games are free and you don't need to create giveaways for them nor spend your points on them.

First of all these are Steam's offers. They are free if you met the requirements and most of them just require you to have a Steam account. Also I learned that Source SDK is free now so nearly all of the games on that list are free without restrictions.

I hope after this point nobody will post these games nor enter giveaways featuring them. I think it would be best to make this or something like this sticky or add it to the faq.
