Suggestions:
In general: I really like the singularity power plant design: Big bonus to local planet, decent bonus to empire. Would not mind seeing that in all the wonders.
Omega research center: Change to 200% research to local planet, 25% research to Global. 5% research per level to Global. Make it no longer a upgrade from innovation complex. Add a new tier 3 research boost building similar to quantum power plant/financial sector. basically make it more like singularity power plant.
Cultural Beacon: change to 25% influence. remove influence on galactic showcase. maybe add big influence to local planet.
Shrine of Tandis: increase adjacency bonus to 2 to be on par with virtual world, or 3 to be special snowflake wonder.
Galactic showcase: remove influence, up adjacency to 2. Add 200% gross income to local planet, like singularity plant.
Galactic bazaar/virtual world/restaurant/tandis: add local bonus too!
Krynnianc Sanctuary should maybe be changed to Player Achievement/one per player, rather then galactic wonder.
