Love the game!

Been tinkering with Gforge, like it so far, but I'm dismayed that artifacts are random and random distributed.

I've got a map in mind once I get a handle on how everything works - it will be based on the novel Mote in God's Eye but it requires 2 things I can't see how to set up:

First, I'd like to disable the ability to research any sort of "leave the vicinity of a star" type research (wormholes, long range jumps, etc.) especially for the AI.

Second, there is an artifact in the game that allows this sort of travel - my plan is to set the artifact up at a specific point (far enough away from the start planets that you don't get it immediately, but not so far away that you've gotten bored looking for it) that will allow the player to jump to another star system.

Is there a way to 1) disable researching specific tech and 2) define absolutely that X planet will have Y artifact and ONLY X planet will ONLY have Y artifact?

Thanks!
