- New colonisation, population, migration, economic, and finance systems. These completely replace vanilla's. Note that mining stations and manual colonisation isn't required.
- New method of ordering ships, priced in credits.
- The pop, tile and building system has mostly been disabled. It'll be renabled in 2.2, with significant adjustment to suit the mod.
- Standard of Living, Approval, Public Order and Economic Efficiency mechanics.
- UI changes.
- Management practically removed from planets for now. 2.2 will see core worlds become more interesting again.


- Science has a fixed ouput, influenced by leaders, tech, and the Education empire policy. There are however no penalties from pops, colonies and systems.
- Unity starts at its base rate and is improved via tech. Like science, it doesn't accrue penalties for empire population/size.
- Food is redundant, and minerals have limited use.
- There's a new megastructure - the Dyson swarm. It can be build in systems with higher populations (initially basically limited to the home system), attracts a very high amount of immigration, and allows population to grow at a higher rate than normal colonies.
- Planetary shields work differently, now having hitpoints. Initially it offers complete protection, but as it becomes heavily damaged, it starts letting increasing amounts of damage through.
- Population can be annhilated by bombardment.


- Survey speed is a third of vanilla, to slow the exploration phase down a little.
- Outposts are twice as expensive, to slow expansion down a little (it's still fine).
- Science has a flat production rate, adjusted by the Education policy, techs etc. There are no pop, colony or system quantity penalties.
- Unity has it's base rate and tech can improve it. Like science, it has no pop/colony/system penalties to overcome.
- FTL is been slowed significantly, and on average travel takes about twice as long as in vanilla.
- Cruisers and battleships are available a bit earlier. Crusiers are a tier 1 tech, and battleships tier 2.

This list contains more changes than I can remember off-hand, so I'll add to it over time.
