I am working on a mod and from playtesting the game some techs I do not want used have been turning on later in the game, for instance I am being attacked in the musket age by SAM infantry. I have tagged all the later techs with TECH_FUTURE_TECH, so they will need to have future tech as a prerequisite before they can be used. Will this work, or do I have to completely remove all the techs I am not using from the tech tree? I am hoping I do not have to go through the trouble of taking all these techs out. Thanks for any help.
