I don't know how to tell what I gave them. I could have given them my missile tech, defence tech, or even large hulls. It should at least tell me what I gave away, don't you think?

The events tab only shows what I recieved, and only by saying that research on each of the techs was completed. For those interested, here are the techs I recieved:

Ultimate Logistics
Advanced Life Support
Shield Defense Theory
Laser
Habitat Improvement
Singularity Driver II
Singularity Driver III
Soil Enhancement
Missile Weapon Theory
Extended Life Support
Beam Weapon Theory
Xeno Ethics
Diplomatic Relations

I don't notice any particular system to it either. I figure it is most likely random. Again, not so great getting Xeno Ethics before I was ready. Some of those are high dollar (at this point in my game) techs that normally would be difficult to get from the AI as well.

Not at all. I can think of several situations where I would rather give up higher-RP techs to protect specific things, like techs that give passive bonuses, unlock a trade good, a specific colonization tech (yes, I've had this come up that early before), etc. This would vary between games, so the most valuable techs can't easily be determined. OTOH, you could use selected techs to screw with the AI - Industrial Sectors for everyone, now spend eternity upgrading!

If instead of random techs, the game gave you a list of eligible techs (those that enough other civs haven't researched so sharing them would benefit nearly everyone) it would add a bit of depth to the event. Although, if any changes were to be made to the UP, this would be pretty low on the list, compared to things like having a say on what issue to bring up at the meeting.

I'm not saying I'd do it all the time. All else being equal, of course I would give away the cheap stuff. But you can tell from the tech list above, SOMEONE gave away some really cheap crud - beam/missile weapon theory compared to ultimate logistics?

That's why I suggested being able to pick from a list of "eligible" techs, say the techs that you have but less than half of the AIs have. To be fair, you would have to pick the techs you give away before you see what everyone else is sharing, to prevent duplication (if someone else is giving away xeno ethics for ex., you could pick that to effectively get out of giving one tech away).

If I must give away weapons tech, I'd rather give singularity drivers 1, 2, and 3, rather than the random choice that will give the AIs SD 3 and two other techs. It's technically possible this could happen anyway (SD 2 and 3, beam weapon theory and laser from the above list) but I'd rather be able to deliberately choose to do it.

At a bare minimum, we should at least be told what we gave away, even if we don't get to control it.

"At a bare minimum, we should at least be told what we gave away, even if we don't get to control it."

This is, in my opinion, critical. I have no way of knowing if I just volunteered the tech that was winning me the war. Speaking of which, in this game the AI can now suddenly run around the galaxy at warp speed (6 mp), when they were stuck at 2 or 3 mp. Wonder how that happened?
