I am rather interested in ArcheAge. It's been a good opportunity to get out there and play the alpha when I've had the chance! I'd been hearing about AA for a good long while from one of my closest friends and now I understand why he was anticipating it for so long!
I've been wandering through several other MMOs in the past. The first one I was actively roleplaying in was Aion and spent nearly four years playing that. I then took seat in Tera for a year or so. Additionally, I took short vacations to SWTOR, WoW, FFXIV, Rift, and a few free to play games but didn't find any of those to hold my interests.
I am truly excited to see more about this world and the opportunities to build storyline. I haven't quite figured out my own characters just yet but I will be ready soon!
