Simply put: It's my opinion that the current state of the game is "not fun".
To start: Random placement of usable tiles and capitals (significant because of the adjacency system), random number and placement of tiles with Arable Land (exacerbates the problems of the adjacency system), and random access to resources (significant because of the construction requirements of one-per-galaxy wonders).
I've made a tentative effort to make the game fun again:
I'm playing a test game, and results are good so far: Much of the RNG-screw and associated micromanagement has been alleviated, and the game is better for it.
But obviously I'm not using all abilities, techs, etc - I'm interested in suggestions concerning how other improvements should be adjusted due to the removal of the adjacency system.
For example, the Bureaucrats line of improvements seem to provide only adjacency bonuses. What should be added to these buildings to replace the removed bonuses? Which other improvements provide only adjacency bonuses, and what should be added to them?
Are there any improvements that become strictly inferior to alternatives with the removal of adjacency bonuses, and how should they be adjusted to remain interesting choices?
Aeroponic Farm: Is +3 food production enough to make the Aeroponics ability at least somewhat interesting? Should the effect be increased to +4 food production to compete with some of the stronger abilities?
Modding tips would also be welcome. There don't seem to be many modding resources for the game, and making the mod has been a "so how does this work?" sort of affair.
