If I remember correctly, the original plan for Entrenchment was that people with Entrenchment would be able to see Regular Sins games and then be able to join them and Entrenchment just wouldn't operate, or maybe the idea was that everyone could see all of the games and if someone without Entrenchment joins, it plays as regular Sins, or perhaps hosts could check off whether or not to allow them to join.
Anyway, the regular-Sins-Entrenchment split has divided the already tiny online multiplayer community. What will Diplomacy do to it?
Will people who have BOTH Diplomacy and Entrenchment be able to see Diplomacy-only, Entrenchment-only, and regular Sins games? Will people who only have Diplomacy but not Entrenchment be able to see Diplomacy-Entrenchment, Entrenchment only, and regular Sins games?
Will having Entrenchment be required as a prerequisite for installing Diplomacy?
