Just joined the forums today because I was hoping it was still active. Pleasantly suprised that one of my favorite maps is still being worked on =p.
I would like to say that having a save/load system wouldn't be popular for the blizzard crowd, but for a small niche it would be grand. I've been trying to do a persistent, session based kind of roleplay for some time, but its difficult to have that continuity when everyone has to level again each new session.
It would allow things like politics to really progress though. You could have people changing the throne back and fourth without a major issue. I feel like alot of the content of this game comes from the player's interacting, less than the game content itself.
Perhaps a save/load version released on its own might be possible? I used to mess around with the map editor, so I can certainly understand that it wouldn't be easy to keep updated and implemented.
