I have a game and has a giveway of his trilogy!/tenho um jogo e tem uma giveway da trilogia dele!

What?

Umm, I don't understand the question here?

You mean you have one game in the trilogy, and you're asking if you can enter the giveaway for all 3?

You're asking the wrong people. Ask the giveaway creator directly through his giveaway, it's his decision

I'm assuming you have sniper elite 1 and are wondering if its ok to enter a giveaway for the trilogy?

Check the description/comments. Usually the creator answers it. Personally I'd feel it would be ok since its the first one...hell even the 2nd one since that was given out for free(I think).

From the FAQ
"We ask users not to enter giveaways for packages if they already own the majority of the games. This allows for winners that will receive the most value out of their gift. In the end, the giveaway creator has the final say, and if they believe the winner owns too many of the packaged games, we'll allow them to request a new winner."

You wanna giveaway the sniper elite trilogy?

asheiueashiueshiueashiueash people, he wants to enter in a sniper elite trilogy giveaway BUT he has the sniper elite one.
let me handle in my own language because I write faster on PT-BR.

mano, aqui tem muito pouco HU3 BR. evita poster coisa em português aqui que só uma pequena parcela vai ler.
é o seguinte, aqui funciona assim: pra você entrar no giveaway, REGRA GERAL você tem que ter menos de 50% dos games.
caso o dono do giveaway disser na descrição (dica: sempre leia a descrição) que você não deve entrar se você tiver algum dos jogos do giveaway, é melhor não entrar, senão você vai ganhar nada além de inimizade. se não tiver nada escrito, é a regra geral.
