I was reading the beta patch notes and i didnt see anything regarding the culture/allegiance system.
I really enjoy playing on large, multi-star maps (ancient gifts fore example) but the way the game currently handles culture and allegiance makes playing such large maps extremely difficult, especially when wormholes get involved.
Some things that i think need to be fixed are:
Wormholes, Wormholes just dont work right in terms of expansion. When expanding through wormholes (especially in ancient gifts) the game doesnt recognise them as being any calculable distance from your home planet, and always gives them a distance value of -1. I think that wormholes should act just like regular jumps (as far as allegiance goes).
Empire Size. Maximum allegiance usually drops by 10% for every jump away from the home planet. While this is fine for smaller maps, it usually causes problems with larger maps, or maps where your expansion path is linear rather than having multiple jumps. Ideally the host should be able to set empire size, so we can make use of more resources on larger maps.
