So what exactly is the point of steamgifts.com? Just to be nice? Is it basically just a raffle without actually having to pay anything to enter? What're the "(_P)"s next to the title of the games? Say I wanted to give away Borderlands 2, would the giveaway be open to anybody?
Sorry for the stupid questions, but I just now noticed all those
Well, it's a giveaway site. You give games away.
The P stands for what the retail value of the game is. For example, if you want to enter giveaway for Borderlands 2, the retail value is $60 now, so you'd spend 60P to enter it. It's to stop people from entering EVERY give away at once. You have to be a bit more selective with the ones you enter. Your points regenerate over time though.
Otherwise, it's pretty self-explanatory. You can host an open giveaway, but you can also make the giveaway ONLY open to a certain Steam group (like the CAG Steam Group), and you can also add that only those above a certain contributor level can enter. Your contributor level is just a mirror of how the total value of all the games you've given away, i.e. if you gave away Borderlands 2, and FTL, you'd have $60 + $10 = $70 contributor level.
Hope that answers your questions.
