So i don't have any nifty screen shots but I am sure people can throw some up here.
In Beta 6 I have played three games so far. In all three games I am seeing the AI really has no clue how to build a planet.
in the most recent I found an example of a Research capitol built in a tile with no adjacent tiles. the Research Capitol was the ONLY research building on the planet.
Solar power/fusion power buildings are almost never built next to manufacturing.
Food buildings randomly spaced but not adjacent.
The inability to use adjacency bonuses seems to be a major issue for the AI.
