While modding the techtree, I have come across some...difficulties. The questions are:
1. Can I make one tech dependent on more than one tech? Ex. I want to make it so that Dynamic Shielding can only be researched once Barriers III and Subspace Rebounder are known.
2. Can I make a tech that can only be researched by a specific race?
3. Can I make for example, a tech that can be researched by evil or neutral but not good?
I'm sure I'll think of more later.
