I think we want few things for new megagame:
- CBM, at least pretenders part
- better map, I think Twan did some early work on a big fair map? or was it Pashadawg?
- some nation balance mod would help [just the one taking care of most obvious problems, especially created by very difficult research]
I must say I like diplomacy. I am probably much better at it than real fighting
Lolomos rules wouldn't change much though. In KM I used mostly long-term alliances, not NAPs. NAPs came mostly because of geographical situation on the map - it would be simply very hard to fight wars for me with Lanka or LA Pythium. Wars are also rarely any secret and there was no ganging on each other in the west. 2:1 at most. It woul rather harm east and conquers over there
