I should probably know better than to ask this, but are there any active MMOs that encourage grouping and socialization, especially where you develop a group of friends that you level and grind with? Old school or new are both fine. I recently tried Project: Gorgon, and while it was a unique game with a small and dedicated community, I found that even there, most people soloed or powered through dungeons. I miss the old days of EQ where grouping was basically required, so you ended up making good friends to advance with, and the pace was slow enough that you had time to chat.
Thanks for any advice!
