Unique tech from ruins

It is true that normal techs can give kick off for one player, but unique techs are practically useless except Neural net. And that comes handy only with bigger ships and later in the game.

Actually massive planitary shield has been useful to me. In a PBW game once I wiped out a fleet of 24 ships with one.

I had one small colony planet in a system completely populated by one other player. As often happens diplomacy broke down. Since this planet was all by itself I didn't bother building obital defenceses. But I did build a massive planetary shield and a few weapon platforms.

He was quite shocked when he attacked that planet and was destroyed by my shielded weapon platforms.
