Made Hyper Entertainment Forum, Research Institute and Virtual Combat Arena unlocked to all ethos. In addition, the Grand Mausoleum also gives a bonus of +5 happiness. This is to balance things with the policies being unlocked from ethos, since your pops WILL STILL react to them in accord with their own ethos.

Research labs have been also altered; and behave as the below example:
Example for new lab mechanic, in this case, Physics lab bonuses to Physics, Society and Engineering:
T1: 1 1 1 (basic science lab)
T2: 2 1 1 (Physics Lab I)
T3: 3 1 1 (Physics Lab II)
T4: 4 2 2 (Physics Lab III
T5: 6 3 3 (Physics Lab IV) (Capital world only - the world where you have Empire Capital building)

Game Difficulty options rebalance:
Hard AI bonus to all resources, tech points and fleet capacity reduced from +50% to +25%
Insane AI bonus to all resources, tech points and fleet capacity reduced from +100% to +50%

This has been done to mitigate cheating for the AI, since it can really be Insane even on hard, and yet to also maintain the challenge factor. This is of course still tied to how you expand/colonize and build your infrastructure, but now it won't be as punishing! - more testing needed to be done and input is much appreciated.
