Hmm. I disagree, but I understand. Getting interdicted and escaping a pvp interdiction is probably the most exciting thing in the game right now.
I certainly agree, played many years of UO when it was only open PvP and had some really good times and some tough battles. Playing against other humans vs AI is much more thrilling. However, games like UO/GW etc have strong MP/COOP tools and interfaces. Global chats, party chats, private chats, grouping/party tools, and other interfaces bring people together.
E:D has some very serious problems with making their galaxy feel holistic and integrated as of today. I'm not complaining as I have seen their proposed roadmap and know content patches are coming to address these gaps. When these items come about I'll probably play Open more often then not. Plus, I'm almost at the point where I'm done with making money as I have a nice Viper and an Asp and don't think I want to get anything much bigger.
