Technologies list prerequisites in their data block, but this should be listed in the text as well. Additionally, some techs enable other techs (being prereqs for them). These should list what technologies they enable.

Both of these things should be done with data queries instead of hardcoded listings. –Brend

Linking the prereq tech is easy. Inverse prereqs is a bit harder. What about level 2 prereqs (i.e Tech 1 → requires → Tech 2 → requires → Tech 3), which doesn't exist yet. Regardless, a template edit would be ok. In either case it'd be required all techs are checked to make sure its not double (some techs have and some techs don't have prereq entries now, which is confusing) –Mercury
