Converse with fellow players
Well it's too late now. On Twitter you had to reblog any official tweet from the PSO2 account that had the hashtag "PSO2Givaway" and hope you were amongst the many to be selected. But that ship sailed a couple days ago.
Yeah, that's if you have a Twitter. I have an Instagram for following artists, and the official PSO2 account, but otherwise I avoid social media as of it were the plague. So I don't have a Twitter, mostly because there are some horrible people on there. Not to say that everyone on Twitter is horrible, but there is a subset of users that are bad actors, that like to harass,shame, and berate others, due to perceived wrongs or slights. So when I saw that they were doing an AC giveaway, I didn't bother on trying to win, as there was no point.
