Modding SEV Thread Questions

[Spectarofdeath]

Is there a way for to make a technology tree, but you can't research it, you have to basically get it A) from a event or B) from another race that got it as a event. Once you get the first lvl (from the event) you can then proceed to research the other lvls of the tech?

Also, does this mean the whole idea of being able for a warp point to handle a certain tonnage is in the game?
Warp Point Tonnage Allowed Size Tiny := 100

Edit: Also, is there ruins on planets anymore? I haven't seen any at all.
