In galactic civilizations two. There were a mega event that didn't work for some races. It was the change of heart. The only two I can think of is drengin and korath, bug there could be others like the history of benevolence tech. A problem was tech trees like when drengin changed to good. They were still producing a lot of slaves, and torturing people for entertainment even after a change of heart while still being good.
Two solutions which are badideas while solving this would nerf them. Would be not researching any evil techs, or researching evil techs, but not building evil improvements effectively meeting.
A better solution would be to switch the tech tree. This could be a minor race tech tree, or randomly pick a randomly opposite tech tree. In galactic civilizations this would be easy since everyone had a alignment from gameplay. Now you would have to use the story instead.
Make a neutral tech tree that could be swapped would work. If it was neutral it wouldn't matter if you were good or evil.lidealogies may have the same problem where you may need five tech trees. I like the mega event, but this would make it better.
It would work to start at the beginning of the tree, except if any of your techs are in the tree it would already be highlighted. I don't really like this idea. I think it would be better if you were more equivalent to your tech positions. You could have a tech comparison database. Or you could add up tech points, and device them amongst the paths, or you could add up techs, and device the number amongst the paths being the only exception if both trees have some of the same paths. If this happens add the tech points or techs leading to the tech then minus them from the total techs, or points before deciding them amongst the trees. On deciding you wouldn't device where there are partially filled trees due to the same techs. Certain tech trees would have to be flagged for swap out in some cases. You could if you wanted to do the work even have a different one for each race for each ideology.
If one of my other ideas of combining tech research alongwith this then this would have to be taken into account. This depends how we are going to use combined research.
One way we could do this is the next techs in the paths. From both trees. The unused previous tree doesn't count. You may have before, and after the researched techs with the change of heart race. Now if their are some of thesame techs in both trees. Then the same rule applies where you can't combine research for that same tech, because someone is not advanced enough. A easy answer for this would to gift or trade for the needed tech.
If there is only one new tech tree, or different tech trees depending on how many people combined research. Above rules apply.
If different trees are based on the combination of tech types based on preset values, unless you know how to float this I can't. Then the new idealogy trees count towards this too creating new tech trees.
If myidea for counter equipment on ships based on hostile feelings one or both factions have for each other, or is at war. Like a cold or hot war. Then the units might have to be modified to.
Tell me what you think about this idea.
About the krynn i change my mind instead of researching techs they can still them instead. This would have to be balanced where you may have to start off with more techs. And or this easier to steal techs. You would have to wait for an expansion for this. This would be fine for the krynn as long as it were balanced.
