Racial techs, defined as being the ones you get when you pay race setup points for them.

Let A be a racial tech
Let B be a normal tech, that has as a prerequisite, tech A level X
Let C be a normal tech, that has as a prerequisite, tech B level Y

If you paid the race setup points, you can research it normally.
If you did not:
- You can NEVER get any of tech A.
- You can never research any of tech B. But you can steal it from other players who have it.
- You can research tech C, but only if you have previously stolen level Y in tech B.

Note:
In the unmodded game, all technologies are either of Type A, or are normal techs available to everybody.

Note 2:
If you uncheck the "allowable tech" box, then NOBODY can ever research that tech.
