Aw, I loved Hibbies. Celtic lore is definitely my favorite out of the three. If the game wasn't a shadow of its former self I would still be playing it today.
I might try Dominus. I am a fan of the large-scale RvR model that Dark Age was famous for, so if this game is anything close to it, it would be worth checking out. Although personally, I'm hoping Guild Wars 2 fills the PvP shaped hole in my heart. That, and I tend to lean more towards fantasy than sci-fi.
